BAD (OR RATHER, NO) CUSTOMER SERVICE!!!!

I am a client of booking.com and they issued a virtual credit card for an on line payment that a guest made on 2 April 2023. I cannot use the virtual credit card, because my POS machine must have the actual card presented. I cannot get a proper response from them! It is mostly automated or , when I contact the international call center (at my cost), I get a different agent every time and they all tell me different stories! They are absolutely useless!
