"Do you have a screen shot?" That is what you'll be asked for to prove anything to their customer service. I rented a SUV that had an offer of "free second driver and GPS rental" showing on the website. When I received my final booking it was not there. Customer service refused to honor the offer because I did not have a screen shot. The vehicle I had selected was no longer showing on their site. I had no "proof". Just my word. A different vehicle, much more expensive, from the same supplier did show the same offer but they still refused to change my rental. Make sure you have proof if you decide to rent from them. Bait and switch? Maybe. Bad business practices? Absolutely!
