MTN not sorting out crucial upgrade error.

I upgraded my number in December 2020. I was told that with the tablet device I will only get data that will be pre-loaded on my account. 8GB. I was fine with this and asked the lady that assisted me at the MTN Eastgate Branch to make sure that I can still purchase my voice and data and SMS's over and above the package that I am taking as I usually just top up with something when I run out.

What they have done and did not warn or tell me is to change my contract to a data sim only package. This has resulted in me not being able to purchase data, SMS's or voice minutes on my contract using my airtime as I have been doing for years. I have phoned and logged numerous calls and queries only to ever be told by MTN that they are investigating and they never revert back to me with a resolution. I have now struggled for 22 days straight with this issue without any help from MTN whatsoever.

MTN needs to either update or migrate my package to include the ability to purchase and convert airtime into the data, voice and SMSs bundle specials as per all their USSD codes and MTN apps so I can use this contract as it was intended to. The only alternative is cancelling the contract effectively ending a near 20-year relationship which I am not in favour of. (MTN will need to absorb cancellation fees in this case as this was not my fault or doing) I don't have any more options to my disposal. I am now forced into a corner.
