Direct TV dispute: lawsuit?

The HD DVR in my bedroom had been messed up since September. I travel a lot and waiting for hours for customer service is ridiculous with this company. I sent several email complaints as well and their response was to reset the receiver (which I'd already done per their lame advice). Finally after 3 months of no activity I tried to cancel and demanded they not charge me for the months of service I couldn't use. (Whenever anything would DVR it would tape the HD channels which were all blank gray screens). Well after filing complaints to the BBB etc they returned $16 or something insulting. To really put the icing on the cake, I had been threatening legal action and they held their stance and after all of that was said and done... they TOOK the remaining $208.52 out of my bank account UNAUTHORIZED!!! I was on vacation last week and received an email notification to confirm the authorization.

Has anyone else had this problem? I suspect they did this to a lot of people owing them money especially since it was at the end of a fiscal year. How do I go about filing a lawsuit for this? I have money, that is hardly the issue... I'll spend 10 times the amount I owe them to let consumers know what a crappy company this is and how terrible they treat their clients.
