Ok, totally unsympathetic, I've been using godaddy for 12 years now and never made this mistake before, very disappointed:

Dear Jonathan,

Unfortunately, we are unable to cancel your offer as this will have a negative impact on the auction, the seller, and the other members participating in the auction. Your offer is a binding contract as stated in the GoDaddy Domain Auction Membership Agreement you accepted when confirming your offer for this domain. You are expected to pay for the domain if the seller accepts your offer. Offers are good for 7 days so if the seller does not accept your offer or push the listing to auction by 1/13/2018 then you will no longer be obligated to pay. Please let us know if you have any additional questions.

Regards,

Lisa
