Unhelpful service

My Mom that is almost 70 and took out a new pc and wi-fi router contract 11 days ago. Since then there has been problem after problem and no one seems to be willing or competent to sort this out. She is sent from one person to the next with no joy! We have been to Vodacom Woodlands 9 times in the last 11 days. On Saturday after going to Incredible connexion for help we were told by someone there that there is sometrhing wrong with the hardware. Went back to Vodacom and they told us to phone HP and when we phoned HP they said there is nothing wrong with the pc. My mother went back to Vodacom and was sent again from person to person with no results. Had to go back to Incredible connexion again to get someone to help her load Windows office again as Vodacom apparently does not help with that. Only to get home and the internet is not working again!!!
