I'm thinking that without the serial number written down on the paper work could be a problem, I shouldn't but could be. Just remember (some else has mentioned) work of mouth can be the dealer's best freind or worst enemy. One suggestion I would have, you may know this already, is to keep calm when trying to straighten this out. I deal with people not doing the job, ordering parts, looking up information, delivery problems ect. I would try to keep a smile, be very polite, be freindly. I know this is hard to do (I know because I can fly of the handle pretty easily/w3tcompact/icons/blush.gif). Give it a try it's amazing what it can bring. Another thing that this helps is helps keep you calmer (somewhat) and keep you from saying stuff you may regret. Believe me, if this happened to me I would fly of the handle too. One last thing, I do think that the dealer is very dishonest. There could be just a communication problem with in the dealer, some else was looking buying the same time you where. But the dealer should have (as you mentioned) called and explained the situation to you. If you can't get what you want, get your money back and shop somewhere else. I'm sure Carver's would love your business and probably give you a better deal to boot.
Hope all turns out well.
