Drive on holidays are out to take as much money from you as possible!

On pick up drive on holidays wanted a deposit of €2100. There was no mention of this when booking through easy rent cars, only when my booking was completed. I also paid for the collision damage waiver when booking so I was a bit surprised to find I had to pay the €2100 deposit to cover any damages to the vehicle! Drive on holidays then try to get you to take out their damage waiver when picking up the vehicle despite the fact that I have already purchased a damage waiver through easy rent cars. When returning the vehicle I was charged an additional €30 to drop the vehicle off before 8:00am. There was no mention of this during booking or vehicle pick up.
