CarRental8 complaint: Official complaint

I booked a car through your rental website, Booking number: 30830868, for 26/08/2023.
When I arrived in the airport, travelling with my wife and 4year old son, there was no one waiting for me, no answer on the phone number provided in the booking or the phone number on the Internet. I got in contact with one of your customer service representative and after more than 1 hour phone conversation they couldn’t find a different car through your booking systems.

So in order to get a car I had to find another company to rent me a car, which has costed me £ 238.98.
Your company Carrental8 was responsible for providing me with a car on the 26/08/2023 and you have not held your part of the agreement, therefore you are legally liable to pay the full cost of what I had to pay to get a car (£238.98) and I believe there should be a compensation for the delay, stress and all the hassle I had to go through.
