USC cancelling date on us???

Did anyone else have the December 17th USC date?  I got a phone call saying they decided they didn't want to interview on that date anymore because it was so late so they are cancelling it.  Then offered me November 5th and 20th.  Obviously, at this point those two dates are full for me, so I lost the USC interview.  Anyone else in my boat??  Anyone else feel like this is so freaking crappy on their part?
