AT&T Charging for Service provided by MCI

Recently, my accountant raised a question about my phone bill which to be honest I had not previously noticed.

AT&T were submitting monthly charges for a service already charged and provided by MCI. When I raised this question with AT&T they admitted it was incorrect and offered me a refund/credit to the sum of $6.07, the amount of credit they would provide for the remainder of this month. April 2000. What about the other eleven months since last May 5th (1999). Why and how had they charged anyway, for a service provided by MCI and confirmed by my telephone provider BellSouth. No, $6.07 was the maximum credit they would offer.

AT&T Customer service both phone and email, seem to be on the dim side as far as the brain department is concerned. They do not know the meaning of the words "Why and How" and their ability to comprehend a simple question leads me to believe further action is required. I.E., COURT, for seeming to provide a service but not, billing for said service not provided. Obtaining monies by deception, goddammit, outright theft whatever you want to call it. So far, getting a simple answer, has taken two hours of my time without success. What do AT&T's lawyers charge for two hours I wonder. Has anyone else got a similer gripe against AT&T. If enough of us get together we have a good case for a class action suit against AT&T. Maybe then, AT&T will sit up and listen to us the consumer. Us, that put AT&T where they are today.
