Everythings perfect and I really love this game but the thing is I kept on losing my account. I lost my first one and reached out to customer service to recover my account, I was hopeless and created a new one and spend my time and money then suddenly I got switched back to my old account, now all my high tier cars, golds and cash left on the new account as I was switched back in my main one. Is there any solution here? Like Login ID and password? So the other one wont reset each time.
