Telkom fails at customer service

My parents are pensioners and their landline has been off-line for almost three weeks now. They contacted Telkom and on 16 Feb 2016 they received an sms to stating that the problem will be addressed (Refer: 45CVZ***6). However nothing was done and they received another sms on 24 Feb 2016 stating that the problem has been addressed, however nothing happened they are still not able to receive any calls on their landline. My mother phoned to indicate that the problem has not been addressed and to date no one has contacted her or have done anything to fix the problem.<br> <br> This not the first time we have experienced problems with Telkom and their weak customer service.
