I just tried to sell my 30 atk Shuppet this afternoon with 20k and someone pm me to buy it, when I replied to him, my message got transfered to the second people, which I didn't notice that he was a false one until I traded with him, before that, I moved the pm and saw the pm of the first people but I thought he was the "second" people. That second people pm me when I typed "ok" and "where are you" with the first people. Before that he said "15k?", which I mentioned that I didn't notice because I was hunting. I accepted and then head to Lilycove to make the trade but realized he just gave 15k, then I said it was 20k but he didn't change the money and, so I declined the trade and checked the messages again, but before I explained he left the pm. I hope I won't get banned because of my mistake. I was playing in my laptop so I didn't have any photos or evidences but I am sure my friends know that I never lie or scam anyone. Thank you for reading, hope you can answer my question about this situation.
Ok, thank you so much for your suggestion.
