I'd tell the broker flat out that he makes it right or you file a complaint with FL real estate board. He needs to agree to arrange a transfer of 300 identical points into your new account.
Or.
He need to reverse the deal at his expense.
He's the broker between the both of you and part of the cost of doing business is to make sure shenanigans don't occur.
Put another way, it's bad for business to have it going around that when deals go bad, his attitude is, "gee, that's too bad..."
I would also put the broker on notice that if he doesn't make it right, you will use every means at your disposal to reverse the funding. If you used a card, I'd work with them. If you used a
DVC or timeshare financing company, I'd protest through them.
Personally, I would NOT sign the waiver with DVC until this is made right. Once signed, the problem goes away for everybody but you. While it's still in limbo, it's festering for all parties involved.
I would let this drag on all parties involved until I got relief.
As a general risk management rule, once companies realize they can't push over the other party in a liability situation, the next best solution is to close out the liability: first priority, get you to sign the waiver and make it go away, backup solution, settle and make it go away..
