Very dissapointed in Telkom ....

I had a problem with my modem over the weekend again - Sunday the technician came out and inform me that my modem was faulty and I had to take in into Alberton City, the shop close to Game, then they will give me a new modem because mine is still under warrantee . Went there yesterday and was told I am at the wrong shop - must go to the shop at the other side of the mall. There I was told that they can't give me a new modem but send it in for repairs and it will take 21 working days. I explain the lady that my sun and I are both studying and we need to do our assignments on a weekly basis. She told me that is not her problem that's how the rules work. While I was sitting there, booking in my faulty modem I got a call from another lady from Telkom telling me that my line was fixed. I told her that I was informed by the technician that the modem was faulty ... now the line is fixed ????? I explained to her as well that I am very upset because we don't have time to wait 21 days because of our studies ... she advised me to rather buy a new one which costs R950.00 ....??? Really ... ????? Can't Telkom help me in the meantime with a modem so that I can at least carry on with my studies .... At the end of the day it seems to me not one cares, the personnel have go no idea what their talking about and the customer get told a lot of nonsense and we must just accept to be unhappy with the service....doesn't matter how this affects you daily life.
