Being charged for a service Im not recieving

I am currently being charged for itemized billing and do not receive them. This issue has now been going on for about 4 months now, every month I call and nothing gets done. The call center cant help me. All they do is log a complaint and after a few days it gets closed even though the issue has not been resolved. This has been going on for months now with no end in sight. If this is not resolved by the end of the month I'm simply taking my account else where. Also when I say resolved I mean that I don't have to call the call center and fight to get my itemized bill. I want it automatically sent as it was with Nashua before and as it is with all the other providers.
