Avoid Europcar and don't get fooled by Discovery Vitality special deal!!

Avoid Europcar and don't get fooled by Discovery Vitality special deal!! Arrived on Saturday midday and collected Toyota Yaris. Then found that the boot does not lock so went back on Sunday morning because it was not an option to leave our luggage in an unlocked car. Returned car on Sunday afternoon. Then get invoice two day later for 903 kms! That is impossible. Had to drive for 9 hours, but no way of challenging two days later.
