Thanks for the thoughts, opionions and reply's. I suspect Judge Roy Bean's observation is on target, in that any information on the check is not read nor acted upon by the payment processing companies. As to a copy of the check still existing, I will wait until I recieve my monthly statement from the bank to see if an image of the check was made. Right now all my bank has is the data from the ACH transaction, [but I still have the duplicate in my checkbook, as well as copies of the correspondance sent them with signatures on the PO Return Reciept.]

I expect to recieve future demands from them, but until then I will rest,.... no, corrrection, I will continue learning from the wonderful people on theis site.
Thanks
