Scotland Highlands NC500

Arrived at 11 PM. It was cold and raining in Edinburgh; only two staff members were working, and they were slow and had an average attitude. I had read about others’ experiences beforehand, so I came prepared with a China Merchants Bank Platinum International Card, embossed, Visa-only, no UnionPay mark. But when picking up the car, they said the card couldn't be used for the deposit; I had to purchase full insurance on the spot to get the car. The insurance payment went through, and they explained that transactions and deposits go through different channels. They didn’t accept cash deposits, and I couldn’t cancel the order at that point, so I ended up paying £600+ for insurance. I saw other Europeans having the same issue when picking up their cars, so it felt like the company makes money off these insurance fees. I’ve never experienced such a scam in other countries. Warning other travelers not to fall for this.
