Bad Service from MTN

A *****ulent celphone contract was taken on my name on the 24th June 2023 after my phone number was sim swapped *****ulently. I went to a MTN Store in Kenilworth Centre Cape Town a ***** case was reported on the 26 of July this is after a debit order of R1,263.70 went off from my bank account to MTN. ***** case ref ***. After that i never had anything everytime i go to the store i am told there is still no response from ***** department. I was then given a *****line number to do my own followups. I called on the 08/10/2023 I was told the metter has been escalated i must call after 21 days. I called on the 13/11/2023 only to be told that it will be escalated again I must do follow up in 2 weeks time. I called today i am still told that this matter will be escalated again i must call after 21 days! This is very frustrating because its affecting my credit score so bad. All i want from MTN is to have that *****ulent contract closed and removed from my name and please have my credit score fixed because i need to buy a car as in yesterday! This is such a bad customer service and its annoying
