No coverage = Cancel new contract

I did not get the coverage promised and thus my contract must be terminated immediately and I'm waiting for the courier to return the router. The guy that helped me (Lizwe) and the next person (Dana) who said the courier will contact me to collect the router is now missing in action. All their phone numbers go on voicemail or just rings. Lizwe ********** and Dana ********** . The two times I did get through to the latter number, I was told they can't help me but that someone who can help me would phone me back. Then no one phones back. I'm not going to pay for something that I can't use. Please stop my new contract for 60 gig p/m @ R359. I'm not going to pay something I can't use.
