Very bad experience

They refused to give me the car pretexting that my credit card is not working, although I have an international credit card with a limit higher than $10,000. Over the past years I rented a car many time and this was the first time I have been refused a car. You should seriously filter your partners as I am suspecting your partner of wrong doing. I am wondering how much cancellation you guys got from this partner. I managed to book another car from one of your partner’s competitors and surprisingly my credit card worked perfectly as you can see on the attached pictures. I already opened a case for that.
