No Line Service for over a week, but I must pay!

Near the end of June, my Telkom phone line and ADSL line went down, it was completely off for 4 days!. (Ref RK290515) I reported it and had no feedback from Telkom, only that it came back on after 4 days. Now the line is down again, (Ref CRK 290615) and its down for 7 days so far, and I can get no information from Telkom 10210, they just keep telling me that it is with the Technician. It costs a fortune holding on with their call centre with my Mobile phone!, Now I want Telkom to give me a refund from their service charge for the period that my line is down. Telkom wont give me any free extra days or weeks on my account, so its only fair that they refund me for the service that I did not receive. if Telkom has to refund all their subscribers for down time, then guess what, there wont be any down time!. as far as I am concerned, Telkom is in breach of contract as they are not giving me the monthly subscription service that I am paying for.
