I booked (and paid in advance) with my credit card a car at Bangkok airport via the rentalcars.com website and I paid the most expensive insurance via the same site. These are affiliates of booming.com. Upon arriving the service provider refused a car on the grounds that my bank cards were not suitable. We therefore lost the entire amount paid and found ourselves at the airport without means of transport. It is therefore an abusive commercial contract, without possible recourse. If you take the time to read reviews you will find that consumers who have been scammed are very numerous. It's downright outrageous.
