Cancelled bid, but cannot edit or end(within 12 hours).
Yes thats right, even if you cancel bids if it's within 12 hrs you cant end the listing.
Is there anything I can do?
Cross your fingers that no one else bids in the last minutes, and learn the rules next time. Never start any item at a price less than you're happy to accept.
