I wish Google would let you change the credit card that you used to pay for the pre-order with.
I just got a replacement 'chip' card for my 'non-chip' car from my credit card company.
If I activate this new card, then the card that I used to place the preorder will be deactivated which would mean that when Google charges my card when they finally ship out the card, it would cause my payment to bounce which would cancel my order after all this waiting.
I contacted Google to see if my concern was valid. She couldn't answer for certain. But, she said that there is a possibility that my order might get canceled.
The only solution I can think of now is to not activate my new card until the phone is shipped out, which based on the customer service rep, is scheduled for Nov 5.
I presume a lot of people in the US would have the same issue, with a lot of Credit Card companies rushing to make the shift to 'Chip' Cards.
Actually, as a side note, Netflix reported today that this 'chip' card transition caused a lot of automatic payments to fail causing a drop in Netflix subscription.
