Ok, the chat function was available when I tried again. Got the $25 credit. I have to chuckle though seeing stories today about how well Google has handled the pre-order this year just because Verizon customers are getting their phones. No, Google totally screwed up the pre-order again this year by sticking it to the people who ordered from the Google store during or soon after the announcement in order to get Verizon customers their phones regardless of when they ordered.
There are bigger things to be outraged over than a phone arriving 2 weeks later than it was supposed to, but this is pretty dang annoying.
