Identify Theft

Hello, I need help with identity theft that was committed. Vodacom had been calling me and saying I owed them money until I went to one of their brunches, at which point they confirmed that the theft had occurred online. I was told to go to the police station to get an affidavit and to fill out their paperwork with my three signatures, which I did, and I sent it to the relevant department. I received a confirmation email stating that I would be contacted, but as of right now, I have not received a call. I have followed up twice without receiving a response.

kindly assist.
