Caldera Car Hire

This is regarding the car rental provided by Caldera Car Hire on 21 August 2022. I am unsatisfied with the service I received as well as the safety and roadworthiness of the 2 cars (total of 3) I was provided with. I have brought this to Booking.com's attention numerous times over the past few months and still no one has reached out to provide a solution or refund.
