So I didn't ask for refund on 29th July, just to have my account closed. Now I'm asking for a refund/rollback to that moment because my account was not closed on my request not by my fault but 1xbit.
1xbit usually scams gamblers for no reason at all which is why asking them to refund your money because they didn't close your account according to your requirements is pointless in my opinion.
They will simply state that the fault lies on your side or they may point out certain rules from their TOS. You should have done your research before investing in this site.
