Incorrect contract loaded. no contract documents to be found.

I went into MTN at Nicolway in April 2019 to upgrade one of cellphone contracts. I took a screen shot of the package i wanted that was on offer that month for an MTN Made for me S contract that includes an iphone 7 64 gig for 24 months.

I spoke to Mbongeni and signed to upgrade my contract to this package with him. He assured me that it was all sorted, premiums would be R399 per month and a copy of my contract would be scanned and emailed to me.

A month later I checked my statement and found I had been billed R649. I called MTN who told me an extra bundle was added and my contract was sold on a 36 month contract. I went back to the store to enquire with Mbongeni who apologized and logged a query online to ask MTN to correct this error he made on the contract and fix it to ensure it will be 24months at R399 and nothing extra.

The reference number was provided to me but still no copy of original signed contract was provided even though it was promised again. I got an sms from MTN saying that the query was resolved but a year later I am still paying twice as much for the contract. No one has been able to find the copy of the documents at MTN (which raises compliance questions) . No one has offered sincere assistance or tried to rectify this matter. The manager at Nicolway has not gotten involved and even taken his staff to task for selling something a client did not sign for and further "losing" the contract that was signed. I will be cancelling all my corporate contracts with MTN as a result
