No ADSL line since March and still paying

On 9 March 2016 our ADSL line stopped working, after confirming with our ISP that the fault was not on their side, we logged a fault with Telkom on 14 March 2016, we then got a sms from Telkom on 15 March to say the fault was fixed, 2 hours later a technician phoned to say he was at the box and the line was faulty, when we got home from work we confirmed that the line was not yet fixed and we contacted the technician to tell him it was still not working, for the rest of March we heard nothing from Telkom. On 4 April 2016 we phoned to have our line transferred as we had moved, only after our old line (which was still not working) was cancelled did we get an sms that the fault had been resolved. We requested a new line for our new unit and on 6 April got an sms that installation was scheduled for 11 April, on 11 April I took leave to be there for the technician but then received a message that it was rescheduled for 25 April, then on 12 April got another sms that installation was scheduled for the 13th, on the 13th got another sms that it was scheduled for the 14th and on the 14th no one came and have also not heard form Telkom. We still have no solution or any news from Telkom
