DEAR TRAVEL TROUBLESHOOTER: I recently booked a rental car with Dollar through Priceline.My car did not have a front or rear license plate, so I had to bring it back to the rental location that night.

Dollar cancels Vivian Everhart’s rental when she tries to swap out an unsatisfactory car. Can she get a refund from the company, or does she have to pay for a car she couldn’t use?
