I will never rent from Hertz UK again. First issue was the +2 hour wait to pick up my reserved car. Second issue was the inability to contact them on their emergency number when we had an issue with the car during our trip. The third issue was a £42.00 fee to simply contact me by email of a parking violation. This fee did not cover the parking violation, only their processing of the contact. I could understand a small fee, such as £5.00 or less, but £42.00 is ridiculous. You may want to immediately cancel your credit card after your trip to avoid being automatically charged.
