Charter unable to supply CableCARD with more than 2 tuner support.

I am having an issue with Charter. My local Charter store only has 2 tuner Motorola M-Cards. They state that they cannot get any other. Talk to Charter nationally and they say they have a 5 tuner Scientific Atlanta card but I have to get it at my local Charter store as they do not have a mechanism in place to mail the card. Go to my local Charter store and they say they cannot get the card. Rinse and repeat. Been trying to get a resolution over the past month to no avail. Even when told that the FCC requires they provide at least a 4 tuner card they say sorry. Did get a Charter area supervisor to call me over a week ago to say they will look into it, but no return phone call and they would not give me any contact information to call or email them back. Very frustrating.
