COSMOTE Mobile Telecommunications S.A. Opiniones 391

If there was a lower rating allowed, they have definitely earned it. Terrible service. A monopoly approach in the year 2026. This is why they do not care of who pays the bill, and therefore their salaries. It is a really sad, sad situation for the customer.

Ότι νάνε. Άλλα λέμε άλλα κάνουν. Δεν τους νοιάζει για τους πελάτες, βαριούνται.

Services beyond trash and the support agents are college kids that know nothing about the technicals. STAY AWAY

Before I signed the contract they told me that in 10 working days I will be connected and more days have passed, I have been left without landline and internet and I have an elderly person who is monitored with a camera and I cannot monitor him without internet, I called customer service and spoke with this employee... who was rude, abrupt nervous and not at all helpful, when I asked him to connect me with the technical service or with someone who knows about the progress of my request, he told me that he is responsible for everything. The worst thing in terms of services and service was the phone call made on 13/03/2026 at 10:41 in the morning to the number 13888 and the employee's name was Dimitris Magd…

Contact was made regarding the renewal of a contract package concerning my two mobile lines, which are connected to a landline (Magenta) that is also registered in my name. However, the renewal, according to COSMOTE, requires the transfer of the mobile lines to unwanted packages (Unlimited, Platinum...), with unspecified charges and duration, until the final transition to the desired Gigamax Unlimited package. Despite my persistence (for more than one hour), the cost of the renewal was never clearly specified, nor was the time required for this process clearly defined, which unilaterally includes intermediate enrollment in unwanted packages until the activation of the final package. This handling by COSMOTE is contrary to the relevant legislation and applicable regulations, specifically: Law 2251/1994 on Consumer Protection (regarding unfair terms and lack of transparency in transactions), the General Authorizations Regulation of the Hellenic Telecommunications and Post Commission concerning the company’s obligations regarding the content of the contract and the right of termination or modification, as well as Law 4967/2022 concerning the protection of contracts for the provision of digital services. The provider, as it is obliged to do, did not provide the financial terms in writing nor the duration of the transition from one contract to the next. As a result, all possible charges (fixed fees, mobile service charges, overage charges) are not clearly specified, although they are required to be stated clearly and without “hidden” costs. This treatment by COSMOTE, particularly toward a consistent customer such as myself, as demonstrably evidenced, is abusive and contrary to the law.

BANDITI SENZA SCRUPOLI
Ho effettuato una ricarica che mi serve SOLO per le chiamate all'estero. Consapevole di questo, Cosmote ha disabilitato le chiamate all'estero, prima abilitate.
Ho chiesto il rimborso, ma nessuno ha risposto, per cui sono stato costretto a rivolgermi a un avvocato, per presentare una denuncia per frode aggravata in commercio

Αχρηστη υπηρεσια. Σου βγαζουν την ψυχη να φερουν τις γραμμες. τα κανουν σκατα με τα καλωδια και τρυπανε τοιχους. Δεν καταγραφουν τις κλησεις για να σε τραβανε με "καντε restart τον router". Ριχνουν την ταχυτητα για να χωρανε ολοι οι συνδρομητες και μετα κανουν τις παπιες. Το support ειναι ανικανο. Σε χρεωνουν για να μιλας στο support.

WORST ONES EVER I LIVE AT THE CENTER OF ATHENS AND THEY HAVE LEFT ME 5 DAYS WITHOUT LANDLINE !!!! AND EVERY DAY THEY SAY WE'LL FIX IT TOMORROW AND TODAY THEY SAID THEY DONT KNOW WHEN THEY'LL FIX IT

Can I go lower than 1 star?
I was litterally told by the staff in the cosmote shop that they could not help me, and was left with a technical issue to solve on my own. Called the customer service multiple times a day to help me add the phone number back into my app as it was removed by their mistake, but was either just disconnected or was told someone would call me back but this never happened. I've seen bad call centers but this reaches the worst of the worst.
If you have any choice, choose another provider- don't get tempted by "the best network" story, as you'll regret it.

Το ένα αστέρι που έβαλα ειναι γιατί δεν εχει μείον μηδέν.
Όταν θέλουν να σου κλείσουν ένα συμβόλαιο σου ταζουν τα καλύτερα και μετά σου στέλνουν έναν εξωφρενικό λογαριασμό με διάφορες δικαιολογίες.
Καταγράφουν τις συνομιλίες μας για την καλύτερη εξυπηρέτηση αλλά εμείς δεν μπορούμε να αποδείξουμε αυτά που μας έχουν τάξει και στο τέλος πληρώνουμε τα διπλά . Η χειρότερη εμπειρία μου μέχρι τώρα και δυστυχώς εκεί που είμαι δεν μπορώ να αλλάξω εταιρεία.

02/03 μας κάλεσαν απο το 13888 για να μας πουν ότι θα περάσουν την επόμενη 03/03 για εγκατάσταση γραμμής απο τις 8.30 μεχρο τις 12.00. Πήγε 14.00, δεν ήρθε κάνεις και κάλεσα ( ε αυξημένη χρεωση) το 5ψηφιο αριθμό να δούμε τι θα γίνει. Η πρώτη εκπρόσωπος με έβαλε σε αναμονή, μετα απο λιγο βγήκε άλλη εκπρόσωπος, έπρεπε να ξαναπώ τα πάντα και με συνεδεσε σε άλλον ,στο "ανάλογο τμήμα " . Συνολικά μίλησα με 3 ατομα, χρεωιμηκα 13 λεπτα κλήσης σε πενταψηφιο , με τον τελευταίο εκπρόσωπο να μου λέει (έπειτα απο επιμονή μου) οτι θα έρθουν ΑΝ ΔΕΝ έχουν τεχνικό πρόβλημα. Παράλληλα χρεώνομαστε πακέτα ίντερνετ στο κινητό για να κανουμε εργασία απο το σπιτι

not stable, bad support

I’d like to put minus 100!!! The worst experience of my life. 4 months I try to put internet in my apartment and still nothing! Today I came from abroad because I received at last message that they’ll come today! I was waiting the whole day and no one appeared! The technical support knows nothing! Awful! And when I said that I want to cancel the application they told me that I’ll have to pay for this cancellation! Though they didn’t do anything for 4 months! The best part of all!
Awful! Awful! Awful!

Very unprofessional and unreliable service. The technician failed to show up within the scheduled time window, and despite multiple calls and reassurances over nearly two months, the installation was never completed. Extremely poor communication and complete disregard for the customer’s time.

I paid for 100mbps for years and got "McDonalds" connection. Unstable with constant errors and "Have you tried to restart" ridiculous customer service that never solves anything. Their infrastructure is garbage. Their Antennas get a 100 errors a day. You can't watch a movie without interrupting it 20 times due to internet connectivity issues. Mobile connection away from Athens is garbage too. On top of that they are the most expensive. Horrible company. Checking my options to move on to a more decent provider. I feel like I'm giving them my hard earned money and they're giving me the finger. By the time I wrote this internet connection was interrupted 3 times lol
