Thank you for taking the time to write this. I am genuinely sorry for the frustration around your order and the follow up experience. Pearl sizing is done within accepted industry ranges, but I understand why it would feel disappointing if what you received did not match your expectations, especially after upgrading. I am also sorry that your overtone preference and post order questions were not addressed as clearly or promptly as they should have been. That is on us, and it is not the experience we aim to provide.
Regarding reviews, we do publish customer feedback on our site. Thankfully we don't have many negative reviews, but if you browse our website reviews you'll see even we don't always get 5-star reviews.
For returns, international shipping costs are unfortunately outside our control, and I understand how that can make an overseas return feel unreasonable. As for the earrings, all of our gold is solid 14k as stated, but sensitivities can vary depending on the mix of alloy used to create the 14kt gold. We find customers with sensitive ears do better with 18kt settings.
