Cancellation

I am trying to cancel my Cell C contract, the Network Signal is pathetic. I entered into the contract for a service which I am not receiving. I cannot even retrieve voice mail at my house with out a 'Call Fail'. My contract expires on the 3/08/2015. I want to cancel my contract at the end of this month and pay the 'handset'/penalty fee which appears to be the same amount as my contract which doesn't make sense I don't want to use this service anymore. I have stuck to this contract by obligation. <br> <br> I have tried to escalate this request but retention department keep telling me they will say the same thing and don't put me through.<br> <br> Can someone please contact me with regard to the above.
