Terrible! Do NOT use them
Shocking - I paid online via debit card, arrived at Schiphol Airport to pick the car up and said they didn't accept debit cards, only credit cards (which I didn't have on me) - despite the fact I had already paid for it from my debit card! They then charged me more than what I originally paid for the rental before I was allowed the keys. It was 10.30 at night, no choice but to do it. Essentially paid over £200 for a £80 car rental. Rip off.
