So if the suspicion substantiated
September 3rd, a scam logically did not happen July 2019!
Yes, you support that a scam happened July 2019!

A scam does not occur at the same time that someone realizes it is a scam. It was a scam from the moment the scammer intended to scam.
So what are you trying to derive from this? "I didn't scam him on July, I scammed him on September"?
