I’ve run into a tricky situation and would like to hear everyone’s thoughts.

While doing a C2C transaction on a certain platform, I encountered this: the other party split the payment into two transfers. I felt something was off, so I asked them to record their screen as proof it was their own operation and to provide a screenshot of their real-name verification. But the seller refused to cooperate, kept stalling with various excuses, and even sent me a payment code asking me to scan it and refund the money or cancel the order.

I refused right away—there’s no way I’d handle money from an unknown source so casually. I thought refunding via the original route would be safest, but WeChat Pay doesn’t even have an original-route refund feature...

Now I’m honestly a bit anxious. What’s the safest way to handle this situation? My biggest worry is if the funds turn out to be problematic, I won’t be able to explain myself. Does anyone with experience have suggestions? Should I contact the platform’s customer service directly, or is there a better approach?
