***** on my name at MTN

I have logged ***** case on 28 December 2020 at MTN store. I never received any feedback until I went for a follow up at the store where I was talk I needed a affidavit from SAPS, of which I did these was 20 January 2021. Up to date I haven't received any feedback , I go to the store every week and I call when ever I get a chance but no seem to be able to help me. I am not happy at all cause I receive SMS's of how much I owe and the airtime usage. I really need this to be resolved.
