How these bookings usually work
The site that took your money handles prepaid refunds
Anything you paid at the counter is handled by the rental company. Counter staff often can't see the travel site's terms.
Site cover isn't the counter's waiver
Protection sold by a booking site usually reimburses you after you've paid. The counter may still offer its own waiver or take a larger deposit.
Changes close to pickup
Same-day changes are usually quicker by phone than online. Your agent tells you exactly who to call and what to ask for.
Refused at the counter? Don't walk away yet
On refundable bookings, if the counter refuses you the car, for example over a card or documents, part of the money can often be refunded, but only if you contact the booking site while you're still at the counter. Very short rentals may not qualify.
Every booking has its own terms. Your agent checks yours before anything is changed.
What your agent does
- Works out who controls your booking and what their terms say
- Tells you what a change or cancellation should cost before you commit
- Tells you exactly who to contact and what to ask for
- Follows up with you until it's confirmed
Questions people ask
Do I contact Booking.com or the rental company?
It depends on what you need. Prepaid amounts and changes usually go through whoever took your money; counter charges go through the rental company. Your agent tells you which, for your booking.
What do I need for the call?
Just your phone. If you have your booking confirmation email nearby, that helps, but you don't need it to request the call.
OneCall Rental is independent and is not affiliated with or endorsed by Booking.com. To contact Booking.com directly, use the details on Booking.com's official website.
Pickup, drop-off, and everything in between. You've always got someone.
