Wants their unit weeks after the auction....

Two auction scenarios (sold 3 weeks ago & all steps followed) - what would you do? 

1. In woman's name, she goes to jail so husband steps in & pays for a year. Follow auction process (I give 8 full weeks notice), sending emails, text messages to both #'s, etc. Husband calls to say he will have it paid before auction. I notify them a few more times with no response. She calls in 2 weeks after asking to pay balance from a DIFFERENT #. 
2. In mans name, items in it are actually alternate's (found out later). I send him (at his request) 2 agreements last summer for her to sign & send back to get it out of his name; never returned it. He calls in upon receiving letter in Feb & says he will pay it prior to sale date. Then calls in night before sale to tell me I am going to keep it & let him make payments. I let him know that if I did that for one I would have to do it for all & I simply was not going to do it. She just called today (3 weeks later & like a letter never went out) & asked if she could pay up the unit. 
8 weeks notice plus letters, emails, multiple text messages, & a notice in the paper 2 weeks straight.
WHY DO THEY THINK THEY CAN CALL & PAY 2-3 WEEKS AFTER THE SALE???
