Can someone help me figure out this Amazon support email?

My Amazon order got stuck and says "Sorry, processing of this order is taking longer than expected" so I emailed them asking what's up and got this response:

Hello xxxxx,

I'm sorry for the delay in completing your order for "Magicka [Download]." As I see you have completed other purchases of software successfully in the past, I have escalated this issue to our technicians to find out exactly what is taking so long. It may also be the result of an upgrade in our system causing things to process more slowly than they normally would, regardless, if you would like to cancel this order or receive a refund please use the link below to confirm:

Please visit the following link to provide the information we requested:

http://www.amazon.com/xxxxxxx

At this time we haven't charged you for your order yet. Once the verification process is complete, we'll send you an e-mail confirming the status of the charge on the order. If the charge doesn't go through, we'll ask you to place a new order with a different credit card.

You can view or change the payment method in your Digital 1-Click settings for future orders on our Help page:

(I censored out the URLs in case they are account specific. The first link takes me to a "More Information, Please" form)

1. Where is the link to cancel?

2. I'm told to visit the first link to provide info they requested. What info? They didn't request any..?
