Excuse me for not using proper report format in my initial post.

What happened::
I bought 1000$ of amazon gift cards from bitcart.io since their prices looked great and had purchased from them half a year ago with no problems. I applied 250$ (x2) cards to one of my familys account and it got closed with account specialists telling me it was due trying to purchase with "invalid" gift cards. When contacted Geeney on whatsapp and forwarding him all the emails I got from amazon accounts department, he told me that he will investigate the "issue", but later he started avoiding me and in the end told me he can't reimburse or do anything since "the account wasn't mine" and instantly blocked me out of whatsapp.
