****mers and *****ulent people

MTN is a **** I took a contract with MTN from 2020 and my contract ended in Dec 2022 with them. On the 9th of Dec 2022 I received a call from of their employee who goes by surname Naidoo I forgot her name telling me she wants to upgrade my contract to 300GB anytime data for R299 I questioned her as to how is possible because the 80GB anytime data I had wasn't sufficient for me as I work full time remotely ans she said because I am upgrading online that was the first red flag I should have thought of but I trusted her. After agreeing to take that 300GB anytime data as she promised I noticed 50GB anytime data and 40GB data for YouTube been loaded to my Sim contract I then immediately called MTN for cancellation and went straight to MTN store in Southgate for cancellation as I was given something that I wasn't promised in Southgate I was advise and shown on the system it's pending cancellation it should be cancelled in no time. I left and few months later I received a call from credit beruae advising me that I owe MTN and I need to pay the balance for me to continue using the data I told them I am not using thta Sim card I last used it in Dec 2022 and I have no contract with MTN as I canceled my contract with them on the 9th of Dec 2022 and I owe MTN nothing. This has been a continuous thing so last year I got a job offer from a certain company and they were running background check on my name and told me I owe MTN and I need to settle the balance and get payment letter I then went to MTN to query this issue with them I was then advised that it will be resolved within 21 days I followed up after 21 working days with no response on the day I went to the store I was given a letter upon request stating that I don't owe MTN anything the regional manager of MTN who goes by the name of Garnet Matsoso I advise that this will be resolved I have been following up with him and he is also not helping me with anything after explaining everything to him now they are saying I must settle the account but why would I settle something I did not even use what kind of *****ulent act is this guy's I can't do anything this is ruining my life I am so stressed out how many opportunities am I going to lose because of MTN ****ming me and I have no such amount I need this be resolved immediately I am going to ombudsman I will do whatever it's takes.
