Telkom lack of care and service yet again

My Mum, a 60 year old of ill healthy lives alone, and is dependent on her landline phone in case of emergencies, has been battling to get help to restore her services. After using the neighbour's phone to contact the call centre several times (and each time she called the Call Centre agents could care less about her need and kept telling her that the matter will be escalated and issue her with another reference number), a technician finally come out, advising that there is an issue with the underground cables and "someone" will contact her but she can't say when...she must just wait! Wait! Sure, for another 3 weeks and pay for a services that you don't receive! I want someone to contact my Mum and resolve this matter ASAP!!!!!
