TopTop Account Recovery Fails After Phone Number Is Unlinked

I am writing about a serious problem with my TopTop account. At around 2:00 a.m. this morning my account was stolen. Now, when I try to log in with my phone number, a completely new account opens instead of my original one, which shows that my original account is no longer linked to my number and has been taken over. This is the second time that my TopTop account is stolen, and I feel very frustrated and do not know what to do anymore. Before the theft, I recharged the account through a local TopTop agent, and he completed the payment by Visa card on the same day, which was a Monday. I still have the recharge screen and proof of successful payment on my device, and I am also using the same device on which the account was originally created. I request that you urgently help me recover my stolen TopTop account, restore full access to me, and secure it so that the thief cannot use it anymore. I am ready to provide any additional information or screenshots you may need to verify that I am the real owner of this account, and I ask you to clearly inform me whether you can restore this account or not.
