6-months long billing dispute

In December I called to find out if the price of our package, which included 2 phone lines, highest speed internet, the top channel package, and the sports add-in, that started at about $270 and had risen to more than $325 / month despite supposedly being fixed, could be reduced.  I was told there was a "special" that would bring it back down to close to the original price.  I repeatedly verified with the customer service rep that we would not lose any channels, internet speed, or any of our existing features such as DVD space, etc. I was assured that we would not, so I approved the change. We immediately lost many of our channels, and the DVD space was cut down to the bare minimum so all of our previously saved recordings were lost as well.  I called back and was informed that we could not be returned to our previous package as we had been "grandfathered" in.  What's more, the price actually increased.  We were told that we could get back most of the channels but the new rate would be nearly $375 / month. 

I have since made numerous calls and spent hours on the phone trying to get our old package back at the previous rate, either directly or as a combination of services.  Each time I have been assured it would be done and each time the price went higher.  It is now over $400 / month.

Your customer service reps are eirher grossly incompetent or have been instructed to tell callers anything to get them off the older packages with no recourse.  I was originally willing to give you the benefit of the doubt, but after these many months I am now inclined to believe this was a scam from the start. 

I'm willing to give you ONE last chance to put this right and credit our account back for the unconsionable overcharges above our original rates.  Don't blow it, because the next stop is the filing of civil and criminal complaints.
