Monfletch has help MANY members here with USPS issues. His knowledge and understanding of these things are ignored at one's own peril.
If you read my post, you will notice that I did not ignore the recommendation given to me. Rather I did do that and I was told something different by my local USPS manager and the person I spoke to at the distribution center and that is all I said on that matter. I do not know who is right but I was given conflicting information.
Update on Issue:
-1st Denial was because the invoice generated by Busse had 2 dates on it. One date was the purchase date and the other date was the date the Invoice was generated. They looked at one and ignored the other - Denial.
-Busse then sent me corrected invoices.
-Corrected Invoices were added to appeal.
-Appeal was denied.
-Spoke to 2 people with Accounting today and they could not give a reason for denial. Letter from USPS gives no reason for denial. All they suggested was that I submit a 2nd appeal which would escalate to an ajudicator.
-I am submitting a 2nd appeal with a letter with detailed explanation of all transactions and invoices.
