From happy to angry and disappointed

I received a message congratulating me on my purchase in December, I was surprised because I only have 2 accounts with Telkom, and have been a happy client for years. So I went to Telkom to check if they might have sent me an sms by mistake, but I found out that there were 3 accounts opened under my name, accounts which I knew nothing about. I was then told to go to the police station and bring all the relavent docs to a Telkom branch (which I did). Things have not yet changed, they did not cancel the accounts, account which I did not open, it’s a fault on their end because they didn’t run their verification process right hence ********* are opening accounts with our credantials. They messed up, and I now have to literally pay for their mistakes. I have moved from a very happy client of Telkom for years to a very unhappy client. Is there someone who can help. Writing on Hello Peter is the last thing I wanted to resort to but no one is helping me ?
