I've been "disqualified" going on 3 weeks now.

I have been "disqualified" I have no idea why. Has this happened to anyone else? I was on PUA since I was only a part-time employee. My benefits are (or so i thought) supposed to end on Dec. 26. I just don't understand why that happened. Is this happening to anyone else? Im currently trying to dispute it. But im not expecting that to much for awhile.
