I have a Dec use year and the points were not showing in my account either, I called MS and explained that I was hoping to add a few days on to a trip that is coming up next week, and I was hoping to not have to borrow to do so. They put me on a fairly long hold to talk to support, but by the end of the call my points were added to my account! So if you need them (and i mean time is running out to have decent availability before the end of may) give MS a call.
