I can see that you just have sent the account details. But where is the proof that he did not pay you? You should provide proof of he is ignoring you or something else. Without the proof, it's unfair to tag him.
But CardSellerN1 can refute this that he paid him by posting the screenshot of his payment the screenshot of the conversation did not tell what really happen it only favors OP, there is still a scroll arrow which means that there is a continuation of the conversation, any one of them can post the whole screenshot.
