I called the concierge line yesterday to apply a SUA to a reservation I made last month. In doing so the concierge notified me that this was a "negative points reservation" and that I would need to deposit more points in my account to ensure this reservation cleared. I was confused because when I originally made the reservation I believe I had the points deducted at the time. This was an 81,000 point reservation, and I also made two other GOH for the same time and dates on the same call. The GOH bookings went through normally. At no point on the call did the agent say anything about a "negative points reservation" or not having enough points.

I believe at the time I had 300,000+ points in my account which should have been more than enough for these three bookings. But I am having a hard time verifying this. In the last 4 months I have made 500,000+ points worth of bookings, and have made a lot of changes, so my account activity is kind of a mess, and hard to navigate.

I obviously don't want to pay this extra 81,000 points that I think I've already paid. But it is hard to show the paper trail of where my points went.

Questions I have:
1) Has anyone else had this issue of a reservation you thought was made with points, but was actually made as a negative points reservation?
2) Is there anyway to check running points balance on the site or app?
3) Is there a way to check on reservations whether bookings are made with points or with a "negative points reservation"? - All my reservations have the same language "Points will be deducted from your account when this reservation is confirmed" whether they are negative points reservations or regular points reservations.
