MTN SA contract cancellation

My contract with MTN ended last year. And was on month ti month as tgey say. 18 August 2022 this year then my bill was double, i phone MTn tgey said the data is no longer on discounted price. Then i said to the so called service champion, lets cancel it. He said i also have to give them a month notice. So my cancellation will be effecting ebd if sept 2022. 6th October 2022 i receive an invoice, since then i have been contacting MTN trying to resolve this issue. And i am not paying for this bill. Someone say the cancellation was logged but never processed. And i must speak to billing department as they transfer me either i will hold for 30min or the voice recording will say the person is not available goodbye. Today now it 3pm, Mtn has been playing games with transferring me to this person or call this number. i have been holding for a manager.

All are recorder is a biggest **** MTN is sekking to us. Those recording are nit available you adk for them. i will repost MTN to all the platforms i can think of and even take legal actions until they resolve this issue and pay back my money.

Everyone in my office is having the same issue. I will request my employer to also cancel my company contract with MTN anf i wi do the same for all my other contracts. Because I cant deal with this unfairness.
