Bad customer service & delayed payment

Hello, over a week ago, I won money on Amazon Slots Ontario. When I tried to withdraw my full, non bonus, cash amount of $2786 into my account, I was asked to show proofnof payment. The site will not allow me to do so. No matter what I attempt, it says it won't support it. I sent countless emails with all of the verification possible. After about 3 days I received one response saying my account was verified and I can withdraw. I instantly checked my account and NOTHING had changed at all. The customer service rep was blatantly lying to me. The account is still stuck at requesting proof of payment and I am at a loss. There is no live chat and no one will take the time to actually help me. My money is in limbo and I fear I will never get out of this trap. I have screen recordings of me attempting to upload documents on my phone and on a laptop. Please help me!

I have been unable to use my funds deposited into Amazon slots account for 2+ weeks now, I have used my account before with no issues however as of lately when I am trying to run any games it is telling me that I am not located in Ontario and it gives me steps to follow, I have followed all of the provided steps on both my mobile device and PC to no avail. I have exhausted all of my options only for it to tell me to contact customer support whom by the way has not gotten back to me for 5 + days as of yet and I have gotten nowhere on this issue.

Amazon slots are withholding my £300 winnings. It is now day 7 and no sign. I finally managed to get an email of amazon on day 4 which stated I needed my card verifying, however I did all this 6 weeks prior and had made numerous withdrawals since then. The worst part about is amazons customer service it is nearly impossible to get a reply off them. Its borderline disgraceful the customer service.
