My son (18) wanted to rent a car. I told him I didn't think any place would rent to him@ that age. He called Kayak & they told him yes & it would cost extra since he was 18. He paid his money, flew to Nashville & was stranded because the car rental place said they don't rent a car to anyone under 25. He called Kayak & they said they don't do refunds. He never received the services he paid for. I'm calling the BBB & he's disputing the payment to them from the bank.
