***** sale no help from gateway or call centre

A ***** sale done on my name was charged extra previous months gateway staff refused to rectify call centre told me to pay the cancellation fees ( for a cell phone I don't have). I called in many time to call centre and still no help my cellphone line is cut of every month as a single mother I plead for help it has effected my credit rating my job my finance. Telkom has been very unfair to me after calling in so many time pleading and crying over the phone they still have not corrected they mistake.
