Okay: First thread on FT (Yipee!)

On Wednesday I sent in six money orders to Capital One in one envelope. The amounts are
$464.11
$494.11
$499.99
$499.99
$499.99
$499.99

I've previously done this successfully and everything was fine.

This time only three of the MOs posted.
$464.11
$494.11
$499.99

They just posted today and I called WU and they said none were cashed (yet). Cap1 support gave me the number to payment investigations but that was all. I do have photocopies of the filled out money orders and a clear paper trail. Should I be worried? Has this happened before? What should I do?

Thank you!

Edit: Now that I think about it perhaps the person manually entering the MOs thought something suspicious is going on? I mean the address I scribbled onto the MOs is not the one on the account (moved) and there were several for the same amount? It's either that or they're in his/her pocket..
