Calls closed but the problem not fixed

Thursday evening my ADSL was working fine, Friday morning my router would not sync with the Telkom line. I logged a call with Telkom for a problem with my ADSL access on Friday morning. The technician came out Saturday and told me my cable needed replacing, he would log it with the relevant section in Telkom. Only to my dismay he just closed the call and left my wires hanging from my wall. I logged another fault Sunday which was closed again on the same day with no explanation. I logged another call with Telkom Monday morning, the technician finally coming out Wednesday. Only the problem is still not resolved. My line wont sync properly. This is because someone changed my port and profile on the DSLAM to a different one. Now the line auto syncs according to what the DSLAM determines. My line was syncing on the old profile and DSLAM at 4.8Mb and download speeds ran at 412kbps. Now it wont even sync at 3.2Mb and download speeds are 200kbps. The technician closed my call and ignored my requests for my port to be changed back to its original settings and DSLAM. I want my service back that I had last Thursday. What do I do???
