Arrived at the car rental company on time, they said the model we booked wasn't available (Hertz explained that the QEEQ website made a mistake; they don't have such vehicles and normally use them for cargo). They offered us two choices: either switch to a 9-seater or change to an SUV and a regular car. However, both options would cost significantly more, and the second option couldn't fit the luggage of our three families, leaving us with only the first option. After dealing with the car rental company and a 2-hour delay, we finally got the 9-seater, but it disrupted our morning plans, and we had to pay extra. After renting cars abroad many times, this was by far the worst experience.

Without any notification, the initial order for a Mercedes was changed to a small Ford. Customer service couldn't resolve it, and we ended up canceling the order out of frustration. They even said they don't accept complaints! An international rental company with such poor service is truly disappointing. In the end, we had to cancel the order, but a Hertz employee came out and offered us a Hyundai for three days at the original four-day price. Overall, this was the worst rental experience abroad.

Charged me for 43gbp because not filling fuel tank. I filled it just car fuel level measure system was broken and showed it incorrectly.

They could not check the car in quickly as it was a 30 day hire. I was there for almost an hour and a half whilst their computer gave problems. They then tried to bill me one day extra at a high day rate when I actually handed it in a day early! They then corrected this but I must look at my statement next month to ensure they did not bill me extra.

Pre-check prior to hire was not rigourous enough - this resulted in me being charged for stowed tyre inflator. This was apparently missing on my returning the van. So it was missing when I drove the vehicle off - unbeknown to me. For stowed (therefore hidden) parts, rental companies should have checklist of items renters need to check before leaving the forecourt. Wholly unreasonable for hire companies to expect renters to have mental list of all hidden equipment (spare tyre, jack, high viz jacket, triangle etc etc) that they need to check before leaving so that they do not get charged excesses on return! I contested this with Hertz and they waived the charge fortunately. But unpleasant.
