What is this scenario?
This is not correct. You may need to get a different person involved, but the system absolutely does have a record of every transaction and it is auditable. Wyndham has not made the investment required to make that auditable record "easily accessible" to Owner Care, but it doesn't mean they can't get to it (will probably involve an account audit over a specified time period, will take awhile, and for those reasons is obviously not their first choice for resolution).
While they may not be able to fix everything systematically that we would like, if you reach the right person in owner care they can be very helpful. I'm sure the right OC rep could help in Adam's situation. Unfortunately I doubt there is anything they can do in Sandi Bo's situation.
I believe you were seeing "ghost" inventory. I had the same thing happen awhile back but had forgotten about it... went through the process, found availability, but couldn't finalize it. So I called in. Some of the inventory that was showing up was there and could be booked by the VC, and other was not. So while I know you were trying to do this when the contact center was closed, did you check back this morning when they opened to see if they could see and book it for you?
