Zakynthos Island Self-Driving Tour

Before renting the car, I specifically contacted the car rental company but did not receive any notice that only credit cards with Visa or MasterChip are accepted. On the rental day, the company said that my credit card with a UnionPay logo could not be used. I asked if my spouse's card could be used, and they said no. When I asked what to do, they said we just need to pay an extra 80 euros to use the credit card with the UnionPay logo and Visa chip. We had two families renting two cars, so we paid an extra 160 euros. Additionally, because the return time was 6 am, outside their business hours, we paid a 24 euro service fee per car. PS: Another Chinese tourist family renting a car at the same time as us also had to pay the 24 euro service fee and a one-month deposit of 1460 euros.
