Vodacom ****s customers

Once again Vodacom is giving us a run around. My wife and myself have been with Vodacom for many, many years renewing our contract every two years - our two cell numbers have never changed. WE are now informed by Vodacom that we are R3300 odd in arrears. How can this be when there is a monthly debit order in place On investigation we find the "monies due ' is for a totally different cell number !! Trying to resolve the issue has been totally ludicrous with Vodacom customer care personnel passing us from one to another and none even mildly interested in helping. This "****" number has obviously been added to our contract by someone in Vodacom that has access to our personal information, yet NO ONE at Vodacom is interested in resolving the issue. Staff at our local Vodacom store refer us to the customer care centre and customer care refer us back to the store. Security at Vodacom is obviously lacking (if there is any at all) and the customer care is nothing more than a three-ring circus. Needless to say, we will not be renewing another contract with them :((
