Bad service and no respect for their clients

I bought a High Sense phone from Foschini in Mall of afrika. I experienced the problem with the phone after 9 days. Took the phone back to Foschini and I was told that it will be booked for repairs. After three weeks received the sms to collect the phone which I did. After a day some problem emanated and I was told that they need to book the phone again. It will take another three weeks for the phone to be sorted. I told them that the reason I bought a phone was because I wanted to use it not to take it up and down the repairs. The manager for Foschini fourways refilwe who was very rude told me that unfortunately I do not have a choice. its either that or nothing. I then decided to call 3G and the lady I spoke to told me about their terms and condition. I asked if this is fair for me since I am still paying for the phone which I am not using. She also told me that its their terms and condition. I asked why was the terms and condition explained to me when I bought the phone since if I knew I would never have bought the phone. This is the bad service ever.
