Unable to use my account for 2 weeks and ongoing

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!

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.

it is rather fair to make other casino players online aware of what is going on with amazon slots.
i am an active customer on many websites and never in my life I've encountered such bad customer service.

it is almost impossible to get hold of anyone at amazon slots regarding delayed payments. i am waiting on a withdrawal which was processed and still no sign of it.

it took amazon slots 4/5 days to verify and process my withdrawn funds. it is now the 7th day and still no sign.

obviously i will be setting strict spending limits on amazon slot and will not be recommending them to friends and family/work colleagues. a good customer makes a great experience but when met with such bad customer service it impossible to stay loyal or spending.
