Vodacom Insist on payment but dont deliver service

On Saturday, 31 January 2015, my Vodacom internet stopped working at home.<br> On Sunday I checked my internet and it was still down so I phoned Vodacom, the operator assured me there is no problem. <br> On Monday I logged a formal complaint with Vodacom Data Support. They called me back to say that they are working on the problem. I follow up on the reference no they gave me 3 times a day. I now have to go and sit in a coffee shop or restaurant in order to do my work, this is costing me a lot of money as I am now forced to buy something whilst sitting here.<br> All they can say is \we are working on the problem
