Making promises and not delivering

I have had a 2mb uncapped ADSL line for the past year and a half. A sales consultant phone me offering me a 4mb uncapped package at R100 more than what I was paying. I signed up, and was told I can collect my router from a telkom direct store, which I did. Configured the account, and shortly after connecting it, my line died. No dialtone what so ever. Logged a call online, and was phoned yesterday just before 12 to tell me a tech has been assigned. No one pitched. Today, after 2 calls again, I was told they would be there before the afternoon was up. Still no show. If I dont get my ADSL on tonight, I am cancelling my contract. <br> GET IT SORTED TELKOM!
