I've been using my Hertz business account otherwise know as a CDP to rent. Have done this successfully as well as shared it with associates to use as well. It got me decent discounts each time I rented as well as other benefits. One of the benefits included in using a business account is free rental days, which is sent in the form of a physical paper voucher to the account owner's mailing address. I've used these vouchers a couple of times successfully, I've also shared one of them with an associate of mine to use once. Then, one day I get notified at the local hertz as well as by mail from hertz that I've been suspended forever otherwise known as being put on the the do not rent list. In their words due to using fraudulent methods to receive a discount. Just to recap, I've been receiving these vouchers by mail and still have the envelopes and even more of these in my car to prove it. Spoke with two people at Hertz and got nowhere....
