Still waiting

I requested my account transferred to my new residence on the 4/06/2015 - I work remotely for a US based company and reply on this connection. Also wanted the line upgraded to 10mbps at the same time. The technician came out on the 17/06/2015, and after spending the entire day in and out trying to get the line to sync, eventually gave up at around 4pm. Note: there was a 2mbps line active and running prior to this at the residence. So the technician said that he would switch everything back to use the old line. Lo and behold, after switching back to the previously WORKING 2mbps line, suddenly that would not sync either. We tested different modems, including the technician's own, the line just didn't want to sync. The day after, the technician phoned to say that he was waiting for another technician to assist him on the exchange. By Friday, still no response - so I phoned him - he then informed me that the exchange was faulty? I then escalated the matter with Telkom. A new chap called me on Friday afternoon to say he would be here Monday morning. It's now 4pm on Monday, I've been without service for 5 days, no feedback, no technician and no joy.
