Poor Service

My mother aged 76, moved last year. We asked that her telephone line should be disconnected and then transferred to her new Address. This was at the end of August 2017. She then got a call telling her that Telkom do not service the area that she moved into and that they cannot help her. She asked the lady what will happen with her contract now as she recently renewed it. The lady told her that Telkom cannot charge her for a service they cannot provide. I tried to call this lady back at ********** but no answer. I called the Telkom service line in Sept. and again in Nov. Last year and was told someone will get back to me which never happened. I called again today and was told that she did not cancel her contract and thus must pay for the rental of the line for the period from Sept. to Jan, even though she did not have a line because Telkom could not provide a line. Tel.no. ********** . She moved From Murrayfield in Pta, to "Kleinfontein Farm" outside Rayton I asked Telkom if they could not provide her with wireless internet but after 3 calls, i still do not have a answer
