Almost scammed by MerryFoxClan

They wanted to purchase my account with a UC Darigan Ixi, they offered $80 but I said $65. They wanted me to go first, I had no problem doing so. I gave them the info to the account, a few minutes went by and I didn't hear anything so I went to check the account and the password was changed I waited a few more minutes, didn't hear back, so I quickly sent the password to my email and changed the password back and pinned it, when I went to check the email they already tried to change it. They feel the need to call me a scammer yet they refused to send the money and already changed everything first. Thankfully I didn't get scammed this time.

 

Do you have any proof that "[email protected]" belongs to him?
