Sir, I was banned only after I request them to delete my account and Instead of deleting the account they banned it.
With all the processing they need (whatever it is) deleting an account looks like not just from a simple button but with different associates and moving some of your basic info to other folders/database, idk if they do it manually or just by a button. But it looks like it need higher ops permission to do it or from technical team not just from a support can do it, so give it few more days to at least 2 weeks.
I understand the concern of the OP, he wanted to have all his info got deleted. Not sure what country though the OP is from, but if he is covered by
https://gdpr.eu/, then the casino have no other choice but to delete his account.
On the other hand, it might take days for the casino to do it. Yes, it's very simply, just go and look for his account and delete everything. However, we have to understand that there are processes in place as well, so give or take maybe at least in a month, everything should be gone in their records or database.
