Made me do another verification when I won big amount after I had already verified my account a month prior

Hi there, I am requesting your help to get my $4000 withdraw from Mr. Bet casino. I have been waiting since March 5 when I requested withdrawal. I was finally emailed a week later telling me I had to verify my account? I just verified my account a month ago and used e-transfer a week earlier for a withdrawal and had no issues with verification since I was already verified! I deposited $10 and won $4000 and all of a sudden I had to do a verification again? I deposit always with e-transfer and some with withdrawals, same email they use to contact me and for my casino sign in, and for the last few withdrawals. Nothing has ever changed. I have submitted every possible document proving that I sent the e-transfer from my account with my account number, full name, phone number and email address. I also sent screenshots of this $10 e-transfer coming out of my account with the provider that they use and also in the e-transfer history page which also shows the e-transfer. I even sent them the receipt from the e-transfer provider that they use which is LOONIO. This email from LOONIO shows the information that the email was sent from and the time that it was sent. All the information on this receipt corresponds with my transaction shown in my account and casino account …date, time, amount. I submitted my bank card also! I submitted my information in my banking with my account number my nam. So with emails back-and-forth with MrBets many Managers, their email is always the exact same and their procedures constantly changing. They requested my bank statement so of course being early March, I had to wait till the end of March so I could provide that to them like they asked for. March 31 I sent them my statement by email I was informed it had to be uploaded in my casino account which I could not do because the verification link was missing and there was an X on the page. In the meanwhile they kept emailing me telling me to verify my account but it took them five days to finally put a new link in my Mr bet account so I could upload my banking statement. I had to upload it three times and it kept coming back saying that my information doesn’t match theirs which is totally impossible?! I have one bank and all I ever send money with is e- transfers using this bank account and everything is correct, so here we go again! it doesn’t matter what I try to do, they’re just making me wait and delaying my payout! So I have been waiting for verification of my bank statement since March 31 and they finally got back to me Monday at 5 AM in the morning saying that it could take 48 hours to verify this or longer depending on their load to be patient now of course I’m thinking I’ve been patient since March 5 where nobody should wait that long for their withdrawal. I was using nothing was different so it has been almost a week and I still have no verification once again! I’ve had it with their excuses and I would greatly appreciate if you could help me get my winnings since I was been waiting since March 5th? That’s way too long and my account was verified already! I like the casino, I like their games and their support are friendly, but this withdrawal and verification is ridiculous. I have submitted everything I can to prove the $10 e-transfer came from my account with my bank statement. I have been a loyal new customer and I don’t feel I deserve all this hassle. I thank you in advance and hope you can help me. And there is nothing else that I could submit to them I have provided everything I can.
