Allow me to register and deposit only to have my account closed due to self exclusion with another brand

I recently joined Shanghai spins. I deposited 200 pounds and played. When I logged back in again it said I am excluded until 2099. I rang support and they advised that I am self excluded from another of their associated site. I didn't realize that the 2 sites were linked. I have requested that my deposits are refunded because if I had won anything worth withdrawing I would not be able to. It seems that cassava enterprise allow self excluded players to open up other accounts deposit and then they get blocked. Win win situation for the casino. Hardly fair gaming
