Lack of truthfulness in the MTN South Africa ***** department

I have received an extremely appalling service from MTN ***** department. On the third of March this year ,I reported ***** involving my MTN account. The ***** entails FIVE cellphones taken thru my account in January this year (2025). This resulted in my monthly bill skyrocketing to more than three times of what it should be. I made several follow up with the ***** department and the issue is not yet resolved. I m getting contrasting responses from the agents that received my calls. One, presumably senior in the unit, sent me a message stating that the ***** has been resolved and my account has been credited. And this is not true because I checked with one of their shops in the neighborhood. I then phoned the ***** department on Tuesday the sixth May asking to speak to the senior staff member who I know by name and surname. I was promised that she will phone me within 2-24hrs. She has not phoned back till today. What a terrible barbaric experience I am going through.
