Blacklisted by MTN

I recently went to the bank to apply for a home loan and was told that I was listed by MTN as a either as a non payment or slow payment. This is now impacting me negatively as the credit department is looking for an explanation about this. The funny part of all of this is that I do not even have any contract or product from MTN.

I then proceeded to call MTN and was struggling to get hold of MTN for almost an hour as you cant speak to a consultant if you do not have a MTN number. I had eventually ended up using a friends number to at lease get hold of customer services. After getting hold of a consultant and explaining my story I was told that I could not be helped by the consultant and this is a credit/legal problem. I asked to be transfer to one of the two departments but was then told that they do not accept calls nor do they have a direct contact number. The only thing the consultant can do is to log a call on the system and credit/legal will get back to me within 48hrs after receiving the notification. The consultant then proceeded to take my details and log the call but to date I've not been contacted by either of these two departments of MTN.

These people do not care about how they impact my life by this decisions and they do not explain this listing as I do not have an account with MTN

Hopelessly waiting till MTN reply one day
