This is a Crazy thing of National and Enterprise. Their DRU (Damage Recovery Unit) sends an empty Incident Report to fill in paper via Fedex.
I returned a car at JFK. Damage was discovered when returned (must have happen at hotel parking lot, not when I was in/near car). I flew out of the US.
They send a paper form via Fedex AND provide Fedex with the email - so Fedex notified me by email it is coming.
If Fedex did not notify me about envelope from Enterprise - this envelope would wait for me for 2 months.
In short - DRU has the email addr - but does NOT use it to send the form to the customer.
