Incorrect billing

The worst experience ever since February this year and still.continuing with no to little joy, gone through every platform referred to and "it does not fall under our jurisdiction" I'm a hospitalized pensioner that had done the run from a to z up until me being hospitalized, with no phone usage at all being suspended because MTN had upgraded me to a package beyond my means so much ad ons that a pensioner would never need, to top it off I have been handed over and still been given the run around, from a package that's to my understanding and was offered for a hundred and odd to Thousand and odd

No phone calls as promised from MTN to date A very upset and frustrated long standing client
