MTN Contract Dispute

Last year around June/July I went in for an upgrade in MTN Tygervalley. After considering a 36 month contract I decided to instead stick with my 24 month contract and upgraded to the Samsung S20+. I made sure that the sales assistant (Anthea Richards) knew that is what I wanted, even asking her after the fact. A few months ago, out of curiosity I checked my upgrade date and it was dated for 3 years time. Me being quite confused called the call centre and checked my contract that I signed (which says 24 months) - the agent however confirmed it was in fact a 36 month contract on the system and advised I need to go into the store. I then went to the Tygervalley branch where my upgrade was done but when I did the upgrade there were Parow Center assistants helping in the store for some or other reason. The agent I spoke to in Tygervalley mailed Stacy Africa to assist in the matter and she had been helping me up until about Jan 2021 and then just went quiet, after which I found out that she went on maternity leave without handing my issue over to her manager. The other issue that arose is that Anthea had used Stacey's logins on the system to do my upgrade instead of her own.

The LEGAL document that I signed was for a 24 month contract NOT a 36 month contract, which is what Anthea actioned on the system. I have been back and forth trying to get this mess fixed, it is absolutely disgusting that I have not had one phone call to rectify this mess, all just emails back and forth and sometimes absolutely no responses at all.
