Have you had confirmation from RCI that the surrender period is over? You say you surrendered last December - is that when you first notified RCI or is that the end of the 12 month surrender period?
Once the surrender period is over, you should get a letter from RCI and new points certificate (if you have weeks ceded into points ) showing your points allocation for future years.
You are supposed to pay any fees due during the surrender period. That is part of the surrender agreement. Having said that, if your surrender period is nearly complete (ie in December 2012) then why pay for the whole year? I would take this up with RCI as they are the ones you are surrendering via. Resort Solutions are acting as a collecting agent for management fees now (as they do for other resorts/clubs). There have been problems with the details given to them by RCI and, as you can see in other posts, people have been sent invoices who shouldn't have been.
If you want, I can check with RCI early next week, as I will be at the RCI Kettering offices on Tuesday.
