There was a major pick up today with American Airlines and they canceled over 2000 flights. I was able to easily cancel my flights and hotel. Both were done via Priceline. Priceline had promoted rentalcars.com and when I contacted rentalcars.com they sent me an email allowed me to cancel. My total rental fee was to be $90 and they charge me seven dollars to cancel. When I called the company they said they could not help me because I had used the email as an option to cancel? They tried to tell me how they called them without using the email they would’ve given me a full refund. When I asked to speak to a supervisor they basically told me to go pound sand and hung up. I will just cancel it to my car and a card. run run run. Otherwise, get ready to lose your money and get bad customer service.
