Auto Europe Complaint - Abusive and unprofessional!
Booked a car through them for 5 days, to use in Spain. There was no mention about any particular fuel policy during the booking process, so one could well assume that this would be the standard "pick up full, return full" policy. Only after I'd paid and received the voucher, I noticed that the fuel policy was an abusive one: you had to buy a full tank of petrol (overpriced even, at almost double the average price per litre!), with no refunds given for any unused petrol at the end of the booking.
I should have seen something like this coming judging by the way the booking went - site broke down and could not handle online bookings, so had to book over the phone, on an international call, with a slow and untrained operator.
