Now its 15 days since they take my money and I see someone else booked the domain at a different registrar.
I really don't care for that domain now as its gone but where I can complaint about these people so they don't continue to scam people.
You'll likely get your money back, PLUS this is the most effective way of preventing them from doing it again. Enough complaints, and they will lose their ability to accept credit cards, and thus the ability to scam in the future.
