Incorrect billing Reference number: ce8fef2b-98d3-4f9e-969d-0c724176b1d2

I had a contract that ended in February 2022 on the number in subject. I called to end contract a month before end date. I was then subscribed to zero rated plan. Since then I have been billed incorrectly and have raised the issue with several consultants. I have escalated the matter several times. My issue is not being resolved and my Services get suspended monthly. I will like Mtn to look into this matter as soon as possible. This affects my credit score negatively as a result I'm unable to upgrade. I'm totally not happy with mtn how my issue has been ignored.

I need this issue resolved.
