Next time, you need to get a picture while you are actually in the middle of the trade so it shows his RSN, and that you handed over the money. With your current picture, it is impossible to know how much you traded and to whom.
However, I am going to ban him based on this:
- The times in the photo seem to match up, beginning with the trade photo that you snapped after the trade was accepted.
- The amount of money left in your money pouch matches up with how much you said you had in total at the beginning of the convo (30M, minus 20M scammed)
- He suddenly claims that you declined the trade and tried to scam him. But because YOU were going first to him, even if you had declined, it wouldn't indicate a scam in any way because you would still have to provide him with the cash before he provided you with the service he promised. I think it is fairly obvious what he tried to do here - which is make it look like you tried to scam him.
Sorry for your loss.
