After many failed attempts , I managed to get almost all the deposit back, I guess is better than nothing

I understand that you managed to get in touch with Razer personally through my last suggested method, by the email subject thingy? I am glad it worked! Albeit a bit too much, but apparently proven to be effective.
As for the received sum is not the exact value of what's being deposited, I think you should better take what you can get. Casinos [including Rollbit] very seriously frowned upon an attempt of abuse, especially self-exclusion circumvention as they have to take gambling responsibly act seriously. Though you're not the one who asked for it [giving you benefits of doubt here] all signs point to it. Indeed, this is a bizzare situation, probably we won't find similar one like this in hundred cases.
Now, as you've receive the fund back and you accepted the amount, I understand you consider it resolved and you have no other issue with Rollbit? I'll ask you to kindly lock this thread to prevent meaningless discussion and mark the title as "resolved". I'm updating the list.
