We rented a compact car from Budget Sheffield via HolidayAutos website to be picked up the next day at 9am. After we have left home to pick up the car, my sister (who was the contact person) received a phonecall from Budget Sheffield saying that the car we requested was not available. We argued that we already have the booking and paid for the car. But Budget Sheffield told us that any refund needs to be requested from Holiday Autos. We then asked for a confirmation email from Budget Sheffield that no car was available. But they told us that we should call Holiday Autos and Holiday Autos can call Budget Sheffield to get the confirmation. Called Holiday Autos who called Budget Sheffield and confirmed that there was no car available. But Holidays Autos did not help us with finding a replacement but told us to make our own arrangements with the local car hire suppliers. And that we should lodge a complaint later for the refund. We had to immediately find a replacement car within a short period of time. Most of the car rental companies had no automatic cars available. Luckily Enterprise Maidenhead was able to arrange for an auto car to be sent from another branch. After the trip, we filed a complaint through Holiday Autos. Holiday Autos came back to us saying that Budget Sheffield claims that we never turned up to pick the car and so there cannot be any refund. As we had no written evidence from Budget Sheffield, we could not refute their claim. Stay away from Budget Sheffield and HolidayAutos! Not to be trusted. We recommend Enterprise instead.
