eBay

Had a non paying bidder opened case no response was given final value fee and buyer given non paying bidder strike ..now showing Payment Pending so looks as if buyer has marked as payment sent because of strike ..will this remove the non paying strik...

Thoughts please on Sellers listing practises as stated on all listingsAny buyer who does not complete transaction with feedback or leaves neg will be blocked from future auctions.Is this against eBay policy ??
