pressure for what? If they have already provided a deadline (and much probably this was not only related to their service) it's just time to wait.
if for all the delays that we have with casino and gambling sites (even reputable) we start creating new topics here on the forum, it ends up that we do nothing but write "to put pressure".
You are making no sense here frankly speaking. Blackjack told op that the investigation could sometimes take more than 6 freaking months and you are saying that it's ok and he should have just waited.
They should have specified a more reasonable timeline(Like a week or 2 weeks) instead. Think!
Imagine how much money you can make for the next six months but the site didn’t allow you to do so because of poor customer service and background checking, this is not unacceptable and we should be alarm gamblers too with regards to this. I don’t know if the CSR is the problem here or the site itself, well this can still affect their reputation and this is not good.
