Not getting any response

My mother using Telkom landline but it's been off since May 2017. Because my mother phone is not working I'm logging calls on behalf of her. This is 1st call logged.Ref no: 182 CWZ 180717 and this was last called logged Ref no: 305CWZ201017 . I have been calling Telkom but they say a technician will come out shortly. An out source company doing the actual work but they said there is nothing they can do Telkom have to come out then Telkom closes the fault logged. I'm really frustrated because my mother have to pay monthly telephone bill but no service.
