MTN CHANGING TERMS AND CONDITIONS OF CONTRACT/AGREEMENT AS THEY PLEASE

Have renewed my subscription with MTN in January 2024 (to the same contract I was on previously), which included a data bundle as well as airtime bundle. I have been allocated my airtime January 2024, February 2024 and March 2024, then without any prior notification was not allocated any further airtime. I only realized when I was unable to make calls. After several calls to MTN customer care, back and forth emails, the MTN agents confirmed they could see the airtime on my profile but no one could explain why my monthly airtime bundle was not allocated to my number. This matter was referred to the Customer Ombudsman and later to the ICASA Complaint division, but to date no resolve. MTN keep denying that airtime is not part of my package even though I have been allocated airtime from January to March 2024. I have requested the recordings of January 2024 where I telephonically renewed my contract with MTN, but I have not been sent this recording till now. I suppose they are playing for time to revert back and say their system does not keep recordings for longer than 6 months! MTN changed the provisions of my contract and what was agreed to without my consent, this is already a breach of customer's trust, and MTN is forcing me to buy additional airtime when this was originally part of the package that I was sold! How can this kind or corporate crime be allowed to take place in today's day and age??? THIS IS SIMPLY ABUSE OF CUSTOMERS. A full breach of contract and agreement. I am locked into this MTN contract for the next two years! this is ********* in so many ways. WELL DONE MTN!
