Now bn is very difficult to use, it cannot be opened at all

A newcomer is consulting, the merchant transferred money to me in two installments, and I requested the merchant to provide a screen recording with real-name information. The merchant just refuses to provide it, keeps delaying, and asks me to scan his payment code to refund and cancel the order. But I refuse to scan for a refund; my intention is that the source of the funds is unclear, and I want to return it through the original route, but the damn WeChat payment cannot be returned through the original route. How should this be handled, I'm a bit worried about being called to sit on the cold bench.
