Vodacom customer care impossible to reach and other reasons why I am planning to leave vodacom

I have 4 contract phones with vodacom. However, there are a few reasons why I would consider another service provider: 1. Vodacom signal in our area is not available during loadshedding and nothing is being done about it apart from excusing SMSs. 2. My wife has a contract which gives her R230 airtime each month. This month, the airtime was drpleted to a left over of R106 by the 2nd of the month. There is no way to retrieve a detailed transaction list to see where the problem lies. 3. CUSTOMER CARE NO. 135 IS IMPOSSIBLE TO GET HOLD OF ANYONE. THE NORMAL EXCUSE IS HIGH CALL VOLUMES, WHICH I DO NOT BUY ANYMORE!!!
