Bad Service

Ref No:EC-0W3X-3WIC2V , I am so not happy about Vodacom , I have never been happy since I started a contract with this company till today , I have been complaining about one thing over 14 Months (wrong billing or Being over charged) I complaint at Menlyn branch was told that charges will be corrected email has been send to complains department , to my surprise nothing was done about my case till date , no feedback was given to me , when I call to find out what is it happening as my line is blocked for more than three months now , was told by one of consultant that my case Ref No:EC-0W3X-3WIC2V is closed , my question is how come can a case bee closed without a customer being informed about the outcome of the query ? I am being threatened about being handed over and being listed on ITC , is this the way you treat your customer ? You busy *****ing money from my bank account every month but you failed to resolve my case. Your service is pathetic honestly. My contact number is ***
