Hello Karsten, sorry for the late response. I saw two questions that are very much the same, and I'll just respond to this one.

I apologize for the hassle you're having with this. Our website automatically detects erratic information from buyers these may include fake names, irregular login activities, mismatched information, and so on. When this happens, the account gets flagged and the payment gets declined. We do not risk potentially fraud payments and transactions in order to protect sellers/users like you, as this could lead to unwanted chargebacks or worse, payments from unauthenticated sources. This ultimately aims to protect you.

For now, I'm afraid I'm going to have to ask you to wait payment from a buyer with a cleared account status. If you have more questions or concerns, please use the Q&A form again and I would be happy to help.
