Bad experience on Bettabets

I have signed up on Bettabets and have tried several times to download my bank statement and id photos back and front for ***. It has failed each and every time so I cannot get my winnings out. It's not much but more than what I deposited. Three if the. Sites went blank after the first spin. I want to deregister myself asap. Not sure if *** is ever going to work as I never had issues elsewhere. Guess I might as well play it out and then kiss them good buy....forever
