This certainly does sound more like a complaint about the alleged lack of expected customer services and customer care rather than a scam accusation. I am not stating Rollbit could not have done more in this particular case but if the OP is upset about the $560 he lost then yes he has a right but this does not make it a scam.
I hope the OP will use this experience as the final push he needed to refrain all types of gambling in future.
In other words, this really isn't a scam accusation, just a complaint without much basis. I understand how problem gambling can wreck lives, OP. I sincerely hope you can get your life back on track if you've suffered any of the consequences of it--and if not, I hope you never learn how bad it can get.
I felt like they make a trap to me. That's why I call it scam. Only one of two accounts were closed, then they confirmed I could play.
Once I deposited and got some profit they deny every withdraw attempt.
When they restored my withdraw function I had no balance anymore. It was a trap im sure, in other words a scam knowing my fragility.
