Telkom service is worse than non-existant

My 96 year old mother-in-law's landline stopped working on the 14 December. After 2 weeks of fault follow up someon told us that the copper wire was ****** and that she should apply for a fixed line look alike, We were told you can only do this at a telkom shop. We app**** in early January 2018 and as of today (26 February) it is still not working. This is despite over 20 phone calls (holding on for a minimum of 15 mins and at one time over an hour) and 4 visits to the Cresta shop (also a minimum of 2 hours per visit). After being **** to by staff members about the availablity of managers and only getting to speak to a manager once. (today) This elderly woman still doesnt have a phone to use. She is not happy using a cell phone as she finds it difficult. What astounds me is the total lack of concern from every staff member, and their "inability" to do anything. how we long for another landline service provider!!
