In April 2021, I rented a Hertz vehicle using my express-b105579">American Express Delta Skymiles Card. One of the benefits is to pay fees not paid by the primary insurance company in case of an accident. In my case, it was a comprehensive claim due to the fact several deer darted in front of my rental and I hit one. I filed a secondary claim with AmEx for the $500 deductible not covered by insurance. All communication was via email. AmEx asked for all sorts of documents and I requested both USAA and Hertz to provide everything AmEx requested. AmEx wanted the most documentation, even more so than USAA. Initially, the $500 claim was paid. Then, AmEx asked for yet more documentation. I was able to speak on the phone to everyone at USAA and Hertz. Both were perplexed by the constant requests for documents that did not exist. I attempted to speak with AmEx, and left messages, but there was never a live person to talk to. Eventually AmEx took back $279 of the paid $500 due to lack of documentation. You never know how good insurance is till you have to use it. I will NEVER USE AN AMEX CARD AGAIN when renting a vehicle. They were high maintenance and non responsive. I have moved to another card for my vehicle rentals, which is around 3-4 per year for pleasure. They are called express-b105579">American Express Assurance Company, and they are a total train wreck.
