Don't know whether or not to play

So, my account was taken by someone else and he bought a score multiplayer pass, I changed the password and went through the entire process with the tanki support team. Now, the verification of whether or not to return those crystals is being done, I don't know if I can play now, because if I do, I would technically be using the score multiplayer pass, but I want the crystals to be returned. I don't know what to do...
