2ND CHANCE OFFER

[maxmillion0_0]

QUICK ANSWER NEEDED PLEASE;

HAVE JUST CLOSED A NON PAYMENT CASE AND SENT 2ND CHANCE OFFER TO UNDERBIDDER. BUT JUST CHECKED SELLING LIST AND THIS HAS COME UP AS A BUY IT NOW FOR ANYONE. 

THATS NOT RIGHT WHAT DID I DO WRONG, DO I FINISH THE LISTING UNTIL THE UNDERBIDDER RESPONDS?
