Telkom Mobile tells me there is \no coverage\""

I moved one street away from where I previously lived, last week Monday. Since then I have been unable to connect to the internet via my cell phone. I have phoned the Telkom help line numerous times and Tweeted Telkom and they always assure me my complaint has been logged and that the technical department will be phoning me. Today I phoned again to be told that there is \no coverage\" in my area and I simply refuse to accept that we should pay for a service we do not get!"
