Pathetic Service and attitude poor customer servic

My issues started when my mum in law n father in law wanted to change over there phone line from my late Aunty in laws name to my father in laws name to change over to Adsl line.... We have been running to the mall of the south store from December with no feedback or luck every months bill that comes is still on my late aunt in laws name, my in laws unfortunately don't have a car to keep going to the I make special trips for Pretoria to take them to the store. Couple weeks back we were back at the store to enquire what the hells going on being promised by your *********** stuff that the change will be done as usual nothing was done again. I am now fed up off this ****py service from Telkom mall of the south who r *********** to carry out there tasks especially Sibusiso who has attitude with elderly clients. Get your **** in order. Give your staff proper training and to resolve elderly people's problems.
