Terrible service and product

Terrible service I have not had a working internet connection since mid October. I have complained and complained and now I'm expected to pay for a service I can't use at all! Their customer service is absolutely terrible. I have explained it to their accounts department several times and told them to listen to the recorded call as all their calls are supposed to be recorded and nothing. I send them a screeshot of the email where the tech says there is a problem with the router and then they email me and ask me how I know there is something wrong with the router. I actually give up. I will not pay for a service I cannot make use of. I might as well move to another company as I have been fighting this for months and im getting nowhere.
