From what I have read seen on different forums and the alike...when it comes to multi accounting, 75% of the time these casino's are never wrong to flag accounts based on multi accounting as they have the flagging techniques in place to find such users because this is their business to stop any possible promo abuse and the alike...just hope your docs haven't been stolen and used for KYC here..
Btw, use of a VPN can get your account flagged as IPs show up on other accounts hence this hurdle..but if nothing in these lines was committed then I trust Rollbit will sort this out asap! Good luck.
I understand this and I have asked them to help me help them. They do not respond and only times they have is same copy paste message: you must tell us your other accounts. I dont have any and I tell them and ask for help and they only ignore. Ive never had issues on any others sites.
