Account been overcharged

Please be advised this account was opened in August last year and ever since I am having endless problems with this account, and NO ONE TODAY CAN ASSIST ME. I ahve been pushed from p**** to post. Cannot get to the Customer Service line , there is no email to complain. I Feed Up and frustrated I now going to COMPLAIN TO THE CUSTOMER PROTECTION ACT. In December I was charged R184.00 for this acoount when it should be R119.00, then I spoke to a lady by the name of Samka at the Pavilion branch who got back to me to advise they found the fault and it will be resolved. Be in mind this line the number starting with 074 is never used there is no mirco sim. Now in January they debited me for amount of R388.00. Tried to get hold of the consultants at the Pavilion (Durban branch ) no such luck she keeps on saying the system is offline. I want to know how can i be cherged for something thats not used. Cell C is the most unfriendly, unhelpful Company anyone can deal with. They JUST DON'T CARE PATHIC SERVICE ALL ROUND.Please contact mer on the CELL Number Provided Urgently.
