Just to be clear to everyone, I have only had one account with Rollbit in my life. I have never multi accounted so there is no way Rollbit can say that is the reason.
I was allowed to deposit and withdraw for months as well and all of a sudden account is disabled out of nowhere. I typically am very courteous to support teams as I know that their jobs are quite stressful but when you receive no explanations from support about what you did wrong, I get a bit frustrated.
The lack of explanation and still no response to emails suggests that they don't care about this case and are content with keeping the funds with their 'Sportsbook abuse and the player is up so they didn't lose anything' claims.
Should I file a complaint with CEG about this or what other recourse is there?
Thanks for the help and support with this it is appreciated.
I would advise you to give a little bit more time, maybe a few days to see if Rollbit representative will come back with better explanation for the concerns and opinion raised by other members here. Far as I know, CEG would also require you to exhaust all possible means of mediation prior to submitting formal complaint to them --I might be wrong, though-- and from other case against Rollbit that I attended to, there were no ADR platform that intermediate Rollbit and also accept sportsbet-related case. So, your chance right now is either this forum or their licensor.
I still stand by my opinion that your case is probably your strategy that they consider as value betting. However, it also worth mentioning that it might be done without such intention and simply a case of innocence, and several members's input here is worth considering, that Rollbit is also partially at fault on this case, because if they don't want such "abuse", they should take a better care of their rakeback system. Thus, based on the narrative this far, the best solution is to let you get your deposit back and you both go separate ways.
But there might be more to this story that's yet to be told. I am still waiting for their representative to give a more in-depth explanation or anything that could contribute to the development of this case. Bottomline, I'm advising you to give it a few more days. But if you decide to directly escalate it to CEG, it's completely in your hand.
