First off - just my opinion, but a motor that has been neglected in terms of oil changes will show signs - sludge, dirty oil pan pickup, etc - seems to me that some basic inspection would indicate that this is not the case, and that the dealer is going out of their way to find a loophole here in order to void the warranty. Honestly, how many casual drivers out there keep receipts from ALL of their oil changes. I certainly don't (but will now, as I also do mine myself).
I know I'm Captain Obvious right now by stating this - just having a hard time understanding why they're claiming it's an issue of neglect here. Plus, your oil level was ok - what, maybe 1/2 a quart low?
p.s. Yes, you can pull receipts from your credit card company. I'd start working on that now as they tend to be slow in retrieving the original receipt data.
