Refund Process / bad service

<p>I have been with cell c for 5 years and have been billed for the last months i've been overcharged in which I have never exceeded before, none of the consultants can tell me why or has no idea what she was doing. On The 27 June 2016, i called the call centre and was told that my case will that 1 week and provided with the the following case number : ********** 200 , a week as passed and nothing happended. No call or sms to let me know if my matter was sorted. On Monday the 04 July 2016 , I called and was told that they will prioritise and was promised feedback by the C.O.B from a Mr. Tshepiso Pooe as he is dealing with my case and same thing i was told today and i'm still waiting my Refund considering on proceeding to the Consumer protection as this is unaceptable and shows poorly on cell</p>
