Spin Away Casino - Crypto deposit never credited to account

On June 13th I made 2 deposits using cryptocurrency, the first one was deposited within 5 minutes. After finishing my balance I deposited another time but this time it did not deposit even though I got confirmation it was successful.

I contacted the chat because it had been over an hour, and I could see my transaction on the Ethereum Explorer, they told me they did not see it in my transactions. My wallet was deducted 2522.91 USDT as you can see in the screenshots, however the amount never got to my casino balance.

I decided to make another deposit the same night, and to my surprise it was in my account in less than 5 minutes. Then I did 2 more deposits and they were all successful. So there is no reason for the deposit of 2522.91 USDT to not be credited to my account, crypto deposits are instant and there should not be any delays.

Now it is over 2 days later, the only message I received is they are contacting the merchant and will give me update. They did not acknowledge the deposit even though I sent them the screenshots with both wallets visible, and there is no sign of progress
