Wow! I got this email from them this morning. Just wow. They are crooks and if they do what they say they may do you can place them on the rogue list. Please see the email:
If we close the investigation as not completed, your deposit will be returned to you but your TonyBet account will be closed permanently and it could not be reopened in the future.“
This sounds really weird statement. If they will carry out investigations regarding to AML/FT etc... they should during that pay you a single dime, as then your deposits (if they would be anyhow illegal and just to make 100% clear, i have no doubt that you would have anything to do with any fraudulent etc... activity, just speculating this and other cases in general and try to figure out what they are doing there).
Not sure anymore what everything you have sent to them, but i personally in your situation after getting these kinds of replies, would pro-actively send kind of source of wealth like your payslip, bank statement and there explained clearly that your deposits are origin of your own incomes, you were advised to use Paysafe as deposit method what you then did and whatever documents you get in mind which could support 100% clearly that you haven't you any stolen money or done any criminal/fraudulent activities to fund your gambling.
Just that this would be next step you are requested. If they have forwarded this to their MLRO, that can take some time, additional proofs could help a little bit (or not) and support people quite surely can't give date when it's confirmed as there also might be some 3rd party included.
But that my first sentence i would really questioning as if they in this moment would refund your deposit, wouldn't it be perfect money laundering if you would be doing it? 100% of your "dirty" money just came 100% clean casino winnings, for sure it's not really complying with AML regulations.
Hope you get it sorted asap, i have no doubt you wouldn't really get paid if you haven't violated any rules or regulations and what you told in full, i can't see anything why you wouldn't get your winnings and yes, i agree this should have been handled faster, only if there is any reason to suspect you about anything and it have been reported, they are not allowed you to tip you about it that it is forwarded for regulation bodies.
About Paysafe, it's not only reason why they are investigating your account, but all anonymous payment methods are automatically categorized higher risk than for example your very own credit card your name on it supported by it's statement. When deposit is coming from method anyone can by with cash, it's impossible to know where it's origin is but winnings you get to your bank account as legitimate casino winnings. That's just one part to take on account when making this kind of investigation and as said earlier, total amount of your withdrawal is quite remarkable only it by self which why they probably want to turn around every stone (i guess they are not making it only to find reason not to pay you if they are owned such o big company these days) and if Betssong group have one (no idea about it) centralized department for these, they might be understaffed time to time as well.
