Cell C - frustrated and ******

Cell C. Had 2 contracts with Cell C, my upgrade was due and popped into Cell C Mall of North. Rose assisted and we came to the conclusion that I should cancel both and upgrade to Pinnacle unlimited. I did all in store. More than a month later I called Cell C to enquire about coverage and was told the second contract was not canceled. Spoke to a Moaxi at cancelations which told me I would be charged 2 statements, but if I go into the store they may rectify. Drove 147km to store, spoke to Dusty. 2h on the phone being transfered from department to department and no luck. Requested to speak to a manager which also ended with no luck. Cell C refuses to rectify a mistake made by a Cell C advisor which leaves me with an additional contract that I did not renew. Also this contract went from R99 to well over R200 a month. Upset, angry and frustrated
