Heart broken and discriminated against by MTN South Africa

MTN has really upset me and I cannot believe the unprofessional and unpleasant service I have received from them. I was meant to do an upgrade on my contract on the 12/12/2025, I called in and was given the run around by one of their retentions staff when I received a billed for R2099 the following day I called in again to follow up with my upgrade to be given the run around again. After many days I was told that it's with the vetting department because my name has changed which is not true I have the same ID since 16 and have only recently gotten my card ID with the same name. Then said okay then please cancel this because I can't afford these charges and was told that the agent that was messing around with my upgrade is the only person that can cancel the upgrade and then I can cancel existing contract. After waiting many days again for them to contact me after being promised to be contacted I called in furious and demanded to cancel only to be told that I need to open a case because my billing is incorrect and I did, last night I received email saying case is closed billing is correct. I called in this morning and was told that I still cannot cancel until I pay the R2099 which I said okay I'll pay you guys in terms because I'm under debt review and I cannot afford a big bill so I made an arrangement to pay and then I said okay please cancel and now they say they still cannot cancel this contract because my account is in collections. Like what the actual hell. I am livid this is actually ************** because I cannot afford to pay so keep billing me until I bleed money. I am a long time customer of MTN and I am utterly disappointed at their service... I'm upset, hurt because I have also had many people from the billing department put the phone down on me. It's actually so upsetting. I hope that if anyone is having financial struggles and they're looking for a cheap contract please don't choose MTN you will only end up crying in the long run.
