Broke my ADSL

I logged a call for the Telephone line being out of order. Telkom sent a technician who fixed the telephone line but broke my ADSL line. I have a 4meg line which always synced at between 3.7 to 3.9 meg. Now the maximum I'm getting is 2.1 meg. My internet was fine before the technician worked on the line. I have logged calls with both Telkom (180BTK200116) and WebAfrica and Telkom said they will have to replace cables in the area? This does not make sense to me as the line was fine before the technician worked on the line. I will be stuck with basically a 2meg line and I'm paying for 4meg. This is not acceptable.
