Poor poor service

I have recently opted for an ADSL line (10mbps) in my flat. After waiting for 6 weeks to get a phone line installed by TELKOM had internet for a few days before the line just went dead. It has now been almost 3 weeks without any solution. My ISP has placed numerous requests through to get it fixed with no luck from TELKOM. I really hope they don't end up charging me for this line rental (which i have not yet had the pleasure of using for more than a few days). I CANT BELIEVE THAT THIS CAN BE ACCEPTABLE ???
