Booked through Discover Cars and something's gone wrong?
Independent help. OneCall Rental is not Discover Cars and can't see your Discover Cars account. We are a Discover Cars affiliate, so if you book through our compare page we may earn a commission. It doesn't change your price or how we help you.
The short answer
Discover Cars took your booking, but a different company hands you the keys. When something goes wrong, each side often says it's the other one's job. That's where people get stuck, and that's where we come in.

If this is you right now
You're at the desk with your voucher. The agent wants a large deposit, or is pushing their own insurance, or says your card won't work. You've already paid, and the queue behind you is growing.
What usually goes wrong
The deposit surprise
Discover Cars says the rental desk can't see its Full Coverage, so you still leave the rental company's standard deposit, on a credit card in the main driver's name with enough limit to cover it.
The insurance push
The desk may tell you that you have no cover. Discover Cars' Full Coverage works by paying you back afterwards, so the desk genuinely can't see it. Discover Cars says you can decline the desk's extra cover as long as you have a credit card for the deposit.
The card problem
A debit card, or a card in someone else's name, can mean no car at the counter, even though the booking is paid.
The refund that never comes
Discover Cars gives a full refund only if you cancel at least 48 hours before pickup. Bookings made inside that window are non-refundable.
Who handles what
Your booking, payment and refund sit with Discover Cars. The car, the deposit and anything at the counter sit with the rental company. Your agent works out which one you need and stays with it until it's sorted.
