internet line disconnected

My telkom fixed line adsl wifi stopped working with a system fault from telkoms side of disconnecting the line , i spoke to numerous call agents and chat agents with not a single one that had helped me , I spoke to a supervisor Caylen from the durban call centre and he promised to call me back , when i called again the agent said hes gone home , i am still paying now for a service that is not working , this is the worst service i got from any service provider , definately going to cancel after this kind of service .
