You cannot remove listings with bids if there are less than 12 hours to go. You can cancel:
http://offer.ebay.co.uk/ws/eBayISAPI.dll?CancelBidShow
and block:
http://offer.ebay.co.uk/ws/eBayISAPI.dll?BidderBlockLogin
their bids. If someone snipes in the final seconds that you don't have a chance to cancel all you can is contact, explain and offer to cancel transaction (at Resolution Centre, bottom of page).
