Landline not working since February 17, 2018.

Good day, My problem with Telkom started on 17 February 2018. tried to send a message to 30591. Received a reply from them saying that it is not working and I have to contact the service provider. I reported the fault many many many times. I received two calls from Telkom . One was from a technician while I was at work. When I explained the problem he said he knows the problem and he can repair it from office, after some time I received an SMS saying that it has been repaired but when I checked my phone was not working. complained again. then someone from Cape Town called me saying that they know about the problem and they are attending to the problem. then I used to get messages daily that they are looking into the problem. but even now the phone is not in working condition. It has been a month, no one can call me on landline and I cannot make calls. But still I have to pay line rental. ( May be they are trying to make profit by not not providing any service). I don't know what to do. Anyone PLEASE HELP. M Thomas ********** 246 / ********** 234
