Yesterday, today, I received a message. The payment was made automatically under my site name. I didn't get any money from them. There is no purchase details on my site. But they say the money was automatically paid under my domain name.
I only use PayPal, and there is no confirmation.
I asked them to ask for cancellation on their credit cards. But it's scary.
How can a swindler use my site name? How should my site deal with this?
