just no interest

i have a problem with my internet line for more then 5 months the call-centre is so very very rude making promise and don't do anything, in 5 months i manage to get 3 technicians to come out for less the 10 minutes at each time messing things up more then what it was before they came, one of them insist it is a main cable in the main box in the street , and that they cant fix it or will report the problem , we work on a commission base only so no work no pay we have people to pay salaries to . but struggle to do the work , telkom agents drop the phone in our ears 1 by 1 or have the phone make a huge noise so we can think its a bad connection , i am really in de-stress , never in my live i had such bad service. now both the area agents that work our area is on leave, so all response is we can not do anything sorry , but i have to pay my telkom and internet line every month , but it is not even working , please help me
