MTN *****

I want to share my utmost disgust with MTN. I am a client for over the past 20 years and have 3 contracts with them. My monthly billing was R858 pm. All of a sudden the debit order amount changes from March 2018 to Nov between R2289 and R2307 per month. Since December the amount changed to R2716 per month. When trying to resolve this issue at a nearby branch I was required to submit proof of ID, address and an affidavit stating my case. I was told that according to their system I have upgraded and also received a new handset! This is totally untrue and I lodged a ***** case. This was done in April already. I have up till today not heard one word back!! I am claiming all my money back with immediate effect otherwise will contact the Ombud. I shall also move my account - this is *****
