It is possible it was an oversight on their part to just close one account and that would have been the one associated with the email address you used to request the account closure. Did you advise Rollbit in that request you wanted both accounts closed? I do sympathise with your situation but can you see the matter from their perspective? If they refund/reimburse you they are effectively telling their customers that doing the same thing will get them refunds too.
I wonder if they will post in this thread offering a solution or their side of the story at least.
Why are you putting words in their mouth? They stated the reverse. They allowed both of the accounts.
So why only closed one of my two accounts and not both?
I understand that point, but it is a failure in their obligation to keep the player away from gambling in their platform.
For some reasons they forbid automatically the creation of new accounts so I see no explanations why did they allow me to deposit and play on the other account.
I believe there aren't many cases like this. Yes Im still waiting for a reply from rollbit representative in this forum.
I sent him 2 messages and so far I got nothing.
