Long term loyal client SEVERELY frustrated and disappointed.

I have been an MTN client for over 5 years now. This is now the final straw with this service provider.

A consultant of theirs called me early December 2022, to tell me that I can "merge" or something my contract - she explained that it will just place me on a different platform and by doing this I will get extra data and minutes. I explained that I do not need it, therefore have no interest in paying a higher premium. She assured me (3 times) that my premium will remain unchanged. Considering my premium will not change I told her to proceed, and again confirmed my premium not changing - to which she agreed.

My next debit order went off, and my premium was DOUBLED! Ever since then i have called into the MTN customer care multiple times, have been given other numbers to call, but no one can help me. I have sent numerous emails and no one has helped me. The only response I got was that you cannot reverse an upgrade, to which I responded and said that I DID NOT GIVE CONSENT TO A HIGHER PREMIUM OR AN UPGRADE.

I still haven't heard anything, and another debit order has gone off. The service is useless and so disappointing, considering I have been a loyal MTN client for years now.
