does anyone else find it frustrating when you have a buyer that bids in the last few seconds, and then fails to contact you??

[wkjm68]

i specify that a buyer is to make contact within 48 hours, and pickup and payment within 5 days.  even after they have bid in the last few seconds, they don't bother to make contact. i often have to send an email or call them  even after the 5 days it was supposed to be collected, to see if they still want the item!

can i re list the item if they don't respond in the time i have asked for??
