Worst ISP ever!!!

I have been trying to program my router since I received it on the 16th April but to no avail. I have refused to pay for a service if I am unable to use it yet I am being billed for it. I have phoned continuously since April and I have been transferred from Customer service to technical to support services and probably wasted R1000 on airtime with absolutely no assistance. I have emailed and WhatsApp messaged until my fingertips are raw. Finally Princess from technical gave me a new IP address to try. Now I can't try it because my service is suspended. My service is suspended because I haven't paid. I haven't paid because it I haven't received SERVICE!!! Please can somebody just cancel this useless account, I want to move to a new ISP !! Please can somebody just help me!!!! Is the a person called Johan Engelbrecht at billing because apparently he can help but he is impossible to get hold of, what's the point!!!!
