Exactly when did the auction end?  eBay allows 3 
*business* days for contact.  You also have to 
allow for the holidays, in this case Independence 
Day, and the weekend.  According to your message, 
you're saying it ended 5 days ago on the 8th, so 
the auction ended on the 3rd?  Well then, today 
(9th) is the 3rd business day.  They have until 
12 midnight PST to contact you.
