Afrihost... what a waste of 5 months

I app**** for my fibre line with Afrihost in February. I am still waiting in June for the Line. According to Afrihost the line is functional but no device has been installed into my house to connect to the fibre line. Everytime I phone the line "mysteriously" cuts out or no one ever gets back to me. I have tried to work with 5 Afrihost employees, none of them get back to me or can help. And on top of all this... they charged me an installation fee and for a months data which I cannot use. I do not know how to resolve this issue.
