I know it took over a week for OP so I'm not too alarmed yet, but what do they need to check exactly?
only they can properly answer that.
Anything over 12 hours to check my account or transaction seems a bit excessive.
it might be, but for them, it's probably a protocol. if they ask you for KYC it might even become longer.
anyway, I wish they(and other gambling sites) would communicate better with their gamblers when issues like this arose, giving only vague answers can really trigger anxiety or can be frustrating especially if it involves a sizable amount of money.
