Unhappy

I have been in communication with cell c since March 2020, as my Identity number was used to **********ly to get a cellphone contract. I have sent all the required documents, i.e. affidavit and copy of my identity so that they can clear my name, still 6 months later I have not heard anything from Cell C, they have blocked my identity number, I cannot open accounts anywhere, when I call them they are sending me from pillar to post. This is so devastating and tiring
