...but it was his incredible rudeness - told me I'm the type of customer he would never want, etc....
When telling us why you didn't like the business, using an "etc" isn't really all that helpful, FWIW. The sentence you said he said IS rotten. And the "etc" might have been good info for us. We weren't there, we don't know.
That said.....
This is all spelled out in the FAQs (I googled the name of the company and am looking through it):
"Once we determine your itinerary is available, we ask for a 10% deposit to book the trip. In the unlikely event that your exact itinerary sells out between receipt of the deposit and acquiring the reservation (through our network of
DVC members), your deposit is, of course, fully refunded."
BUT...
"In most cases, if your trip is more than 7 months away, we require the 10% deposit to check availabilty as reservations that far out require a more manual approach. Just make sure you're serious about your trip, pay your depsosit, and have no worries - if your trip is available, we hold it. If your EXACT trip is not available, we refund your money - plain and simple."
Reading FAQs is a good thing; businesses write them up so that answers are provided before questions are asked, and to save people from worry when they are suddenly asked for something they weren't expecting.
