FWIW I find Amazon's phone support to be faster than the chat stuff. It's usually just a couple mins, most of which time you're on hold while they're fixing it. My wife hates dealing with returns, but I find that it's usually no big deal, and often they'll give you $5 or $10 for your trouble, if things don't get sorted out the first time (which seems to be about 10% of the time).
