i got there an hr early they did not have the car i reserved. they wanted to charge me 80 dollars for for estimated milage . I made sure i had unlimited milage through Kayak.. they wanted to charge me an extra 36 dollars for insurance . i had purchased insurance through a 3rd party using your website. they also wanted to charge me 52 dollars cause i was an hour early. so with what I paid Kayak it was going to cost me around 300 dollars to rent a car that wasn't even in the class of vehicle I reserved. so i decided not to get this rental. so when i got to my destination i went to cancel my reservation. I could no longer cancel this reservation . now im charged with a service of Kayak that i did not use with no ability to cancel so very much will not be going through Kayak for future trips very unsatisfied former customer Danny Elliott
