TELKOM PLEASE IMPROVE YOUR SERVICE THAT WE ARE PAYING FOR!

I have been trying to get my wifi connection repaired or connected with Telkom for 2 weeks. Everytime I call them, it costs me a fortune in calltime as you have to wait for so long to get any reply. After I have given all the details (once again), they tell me either they are working on it or they will check and come back to me and thats as far as I get. I am paying my wifi every month and have not had any for 3 weeks now. PLEASE help.
