Telkom faults not being rectified

Every few months my telkom line goes dead. Which alao has my dsl line going down. Again yesterday Telkom worked on the lines and since then no telephone line or internet. Phoned them early this morning to log the fault. Again phoned at 16:00 as fault was still not fixed. According to them was still testing. 10 minutes later received an SMS that it was resolved. Phoned Telkom again as I still had no line working. They just logged another fault again. Telling me that my user name has changed. Im sure that they have my phone nr used by another household as well because when you dial my nr *** you come out by a Trish. Had this problem now several time over and over and takes weeks to get them to look and send a techician
