Worst Service Provider

I went into the musgrave branch with my daughter at the end of october to migrate my telephone line to that of a prepaid as I felt I was paying too much for something hardly used. The consultant advised that prepaid is no longer an option & convinced me to remain on contract. I enquired about the wifi deals & that I did not wish to exceed my premiums as I am living solely on my pension. She assured me that my total cost incl. 10gb wifi would be R399 ONLY but i am getting bills of high amounts. I have several complaints. 1 is that I was misinformed about the set up of the wifi. To date I have NEVER used it as it never worked. Upon calling telkom several times, they advised that I needed a pc to set it up. I told the consultant at musgrave that I needed wifi to connect my mobile devices & that I did NOT own a pc. She should have told me from the start that I needed a pc to operate it. Secondly, I am getting extremely high bills with two different accounts yet I paid well in advance. Thirdly, the store consultants were abrupt & gave me the run around for three weeks for the router which I had to keep following up with them. I want this sorted out NOW or else I am taking the matter up.
