Hello, we have considered your appeal. According to the Z3X team rules, the account belongs to the card with which it was first used. Accounts are only transferred along with activations from the damaged card.
In your case, you can work with your account without any hassle. Do not share your login/password, then no one else will be able to use it.
Also, when you use all credits from this account, instead of refill your account, buy a new login which you can attach to a working card.
