Unintended error

Hello, the support team. I was explaining in the Facebook group how to use the method of exchanging weapons and taking another weapon when paying 2000 Zp. When I finished writing, I accidentally confirmed 3 weapons and got a weapon. Also, the 2000 Zp discount was deducted. I just don't want that to happen. I was explaining how can weapons be retrieved?

And thank you for support
