Another month has passed & still have problem

I have been posting on Hello Peter every single week and every single week Telkom promises someone will come back to me. Two weeks back they emailed me and asked for my modem details etc, which I supp**** promptly, and now another 2 weeks have passed and the problem has still not been resolved. Please allow me to cancel my contract and go to another service provider that will provide service and give me service delivery and 3g / WIFI that works.
