Got a good deal on a vehicle but customer service ...

Got a good deal on a vehicle but customer service was shady. They wouldn't send documents to look over prior to signing, even after requesting multiple times (we don't live near the dealership), but insisted we could see everything in person when the truck was delivered to our city. Details were different on the document when we finally got it in person vs what was said over the phone and agreed upon, including the sale price, interest rate etc. Unfortunately the hassle to refuse to purchase and continue the search outweighed the disappointment of not getting what was discussed. They wouldn't do anything about it and denied details that were said in our phone conversations. I demanded a copy of what I signed the day the truck was delivered and yet it still wasn't couriered over until after the second or third request the next week (though they assured me it had already been sent, tracking number later showed otherwise). Very poor business practice, not sure I'd ever go back or recommend this dealership except in desperate situations.
