***** resolution channels failing their customers

I recently realised that I've been paying for a *******/fradulent cellphone contract on my Edgars account for more than a year and have been unable to get it resolved since. I've sent emails, but apart from the automatic reply there is no response. Calls to the customer care number is unresolved - that is if you are able to get hold of anyone. I even called the ***** department who referred me back to the customer care number, who gave me another number where nobody ever answers. We don't have an edgars store in our town, so I'm stuck with telephone numbers and email addresses that are not manned property. The avenues available to clients to resolve issues like these clearly does not work?
