Utterly Disappointed and Frustrated by the below par service quality received from Vodacom

I've had a Wi-Fi contract with Vodacom for 2 years and I've been a loyal customer without my account being in arrears. In mid August my number was locked due to an internal sim swop that was done without my knowledge or consent by one of Vodacom's internal staff member. A week later after being given the run around by the call centre agents I was told to go to a Vodacom outlet in order to get my number unlocked (which includes transportation costs which I had to pay for myself and time consuming ). Following the advice given I then went to the vodacom outlet and was forced to pay R64.00 to rectify ********** activity done by their staff-member had to pay. My issue was resolved temporarily. On the 30th August my number was blocked again and customer service informed me that my number has been suspended and i have been calling the call centre since for the past two weeks and all officials i speak to promises to call me back and advise why it's suspended, but no one ever calls bac****! I've been calling them for the past 2 weeks and my issue is still not resolved!!!! The service is absurd. My main frustration is I am being billed for something that I cannot use due to Vodacom staff incompetence. Can someone please rectify this mess other wise I am reporting to your big clients and consumer proctector.
