My plane was delayed and I used the Expedia number to call to let Avis know. I would be arriving late. The agent told me he would call, but it would cost $189.00 for the call and that the airline would cancel my car rental and keep the money involved if I arrive late. Under that understanding I approved the charge. I was surprised when I complained to the Avis agent on the ground to hear that Avis does not charge for calls to let them know I was late. This was an unwarranted and excessive charge for a phone call that took less than 5 minutes. Use them to compare fees, but NEVER use them to book
