Telkom's bad service

I ordered a new 10mb adsl line with Telkom on 13/03/2018. A month later a technician came to install my line. Two weeks after that i received my LIT Tv box. After numerous calls and evetually going into a Telkom store this issue was resolved. I've now had my Telkom line since 06/04/2018 and yesterday my line was suspended!!!!!!!!!! I called the technical department and the sales team and no one can assist me. To make matters worse my bill for this line is R3400!!!!!!!!!!!! how is this possible with a contract of R799 pm???????? Im tired of holding on to the line to get through to accounts department! Ive made numerous calls and everytime I get referred to some other department. Now please tell me how to pay for services I dont have?!!!!!!!!!!! This whole experience of installing an ADSL line has been terrible!!!!!!!!!!!!!!!!!!!
