William Hill Casino Number, Account Suspended

[PokerAmateur4]

I got my account suspended on William Hill Casino when trying to cash out on neteller. I was told this was mostly unheard of on the cryptos, I hit 4 of them though. Any thoughts on what could be up or what I should do?

Also, is this the right number to dial exactly of William Hill Casino, or do I need some code? I keep getting a busy signal and wondered if it was the right number. 011 800 3551 3551
