A very well known dealer (Keep Track Page 1, 
even) claimed he had never received my IPMO.  I 
sent a PayPal payment soon after and filed a 
claim with the post office.  I received a letter 
a month later showing that the MO had been 
cashed. 

I scanned the invoice and emailed it to the 
seller, and he apologized as he had overlooked 
my payment.  I don't think it was intentional (I 
had been doing business with him for nearly 5 
years) and was quick to remedy the problem.  He 
gave me a merchandise credit.   Since I bought 
things from his shop many times, I ended up 
using it eventually.

I suggest contacting the seller and explaining 
what happened (I'd scan a copy of that notice, 
too).  Dealers do make mistakes.  ^_^;

Good luck.
