Telkom account is on another person's name

I have a mobile contract with Telkom. In Oct 2019, I called Telkom contact centre to enquire about a data contract, only to find out that there was 12 additional sims registered on my name, under a person's name T Mashini. I emailed management and received an immediate response, and the numbers were removed from my name. That was awesome!! I did not hesitate to take a second data contract, because the response was really good. On my current data contract, I have not used all the day or night data, but I cannot use the data for some strange reason. I logged a fault, an agent called me, and he could not verify my details, because my contracts are now on T Mashini's name, and the bank account is also reflecting T Mashini!! I am shocked. I am told to go into a Telkom store and verify my account. Will that actually work? I have been a Vodacom customer for the past 20 years, and I have never experienced this. Now instead of finding out why my data is not working, I now realise that my contracts are not even on my name. Can some-one in Telkom tell me what happened? I would really like a response.
