No landline for a month

My mom reported a fault with her home telephone line on 2 January this year. Telkom last communicated with her on 12 January that cables were ****** and it would be a while for them to fix the problem. To date no further update has been given and my parents now have to pay ridiculous cell phone bills as they have no other means of communication. Telkom suggested that a wifi phone could be issued in the meantime but have not contacted them to arrange. I live in Johannesburg and haven't been able to have a meaningful conversation with my parents since New Year! Their follow up service is appalling!!
