LOL! That's a good one!
I don't tend to get excuses, they just don't pay - but I did have a VERY slow payer recently, who - one week post auction - said they'd pay by bank deposit and could I send details.
Problem is, I send out the Bank details in my 'congratulations you have won!' email.....
So I politely said OK, sent another invoice with details, and waited....
A week later, they emailed saying "the bank says the BSB is wrong"
Funny that, because it's the same cut and paste details I send to EVERY buyer! - and I politely told them that.....
A week later, I open a non paying buyer dispute- and four or five days later, the money finally appears!!!
So, not a non payer- but pretty darn close!
