Sorry to hear of your trouble. Whatever your signed contract states you were purchasing is what you are entitled to receive. If it clearly states a certain number of points banked then you have a right to those points or an adjustment to the purchase price (if the points are gone a price adjustment is about the only recourse I suspect is available).
We used Pat at the Timeshare Store and her services were first rate, very professional, prompt and courteous. We would use her again with no hesitation.
Before we went with the Timeshare Store we did a license check with the State of Florida and a BBB check (they are members) to see if their credentials were in good standing and if there were any complaints against them. Their credentials were in good order and their record was clean both with the state and BBB. You can do these searches on the internet.
The time it takes to close depends on many factors -- buyers, agents, sellers, Disney, County clerk, title company, etc. There are many places that a log jam can occur. It might be unfair to single out one party when it is likely that a combination of events have lengthened the process.
We have had problems with real estate closings (personal and business; but not
DVC contracts) and sometimes it has taken months to get the issue(s) worked out. But they do work out.
Give your agent (Pat), the broker (Tom) and the sellers an opportunity to determine what happened and how it can be corrected. It is unlikely that professionals who have worked many years to build a fine reputation would suddenly go bad. And if a mistake was made, and we all make mistakes at times, they will work to make things right.
