Vegas Spins Casino - Withdrawal not processed yet due to previous cool off period with another brand

I signed up with this casino and made a few deposits into the account i also sent in relevant photo id and was sent an email stating this had been all verified, I then made some wins and whilst was playing account was blocked i had an email stating that as part of Casava group i had an old account with a different casino that was under cool off period but that cool of period was 6months and that i had to contact them in relation to having that account reopened so they can reopen this as the full 6months passed a long time ago i contacted them and was advised to wait 48rs Ive sent so many emails to all the depts and not had any luck with getting anywhere i have funds in the account and cannot withdraw them this is shocking!!! and no response even after being advised the issue would be resolved
