I called yesterday to extend our stay at OKW by one day (beginning of stay). I was going to use my VB points (7 month window). I was told that I was one day early and would have to call back today. When I called today, MS told me I would have to call back 7 months from our departure date. What gives! I only wanted to add the one day (majority of our points are OKW). We have adequate points for the one day (VB points).
