Official contact channels
CarJet’s help articles give one phone number, +34 964 830 995, for customer service and for booking extensions. Calls from South Africa go to Spain, so international call rates apply. For written queries, use the contact form in the CarJet help centre at support.carjet.com/hc/en-gb/requests/new, which is linked from carjet.com.
If your booking confirmation email has not arrived after 24 hours, CarJet says it has usually been caught by a spam filter. Check your spam folder first, then contact CarJet through the form or on +34 964 830 995.
What CarJet provides
CarJet is a broker. You book and pay through CarJet, but the car itself is supplied by a local car-hire company at your destination. That matters when something goes wrong, because some questions belong with CarJet and others with the hire company:
- Cancellations: the cancellation policy depends on the hire company’s terms. Prepaid bookings are refundable only if cancelled before the pick-up time on the voucher, and only where the offer terms allow it.
- Extensions: call CarJet, then visit the local rental office to sign a contract extension. CarJet warns that skipping this step may invalidate your insurance.
- Breakdowns and accidents: call the hire company’s emergency number printed on your rental agreement, not CarJet.
- After your rental: queries and comments go through an online form once you have entered your booking details.
How to cancel or extend a CarJet booking
- To cancel, open the cancel link in CarJet’s help article or in your rental voucher and enter your booking details.
- CarJet emails you a link; use it to request the cancellation.
- To extend a booking after pick-up, call +34 964 830 995, then sign the extension at the local rental office.
Address and operating information
CarJet is operated by Gesmarket Internet para Vender S.L., Spanish tax ID (CIF) B12630620, at C/ Ronda Mijares 190 Bis, 12002, Castellon, Spain. CarJet does not publish opening hours for its phone line, and it has no walk-in office in South Africa. Your pick-up and drop-off office is the local hire company’s branch shown on your voucher.
Support and escalation routes
CarJet does not publish a separate complaints or escalation line. Use the help centre form or the +34 964 830 995 line, keep your booking reference to hand, and keep copies of your voucher and rental agreement. For problems with the vehicle itself, deal with the hire company named on your rental agreement.
For other companies, browse the business hub or the business directory C listings.
