bought an account and got scammed less than a day after

yesterday i paid a guy 15m up front on old school to buy a 2 def pure. everything went great and it seemed legit because he's been a member since 2008 and claims he has sold accounts since then... i didn't even have it a day before the password was changed. this is how the deal was supposed to go.
total - 40m
first payment - 15m (yesterday)
second payment was going to be on the 13th and i was going to give another 15m.
and then another 10m around that same time.
he kept the email address registered because that's what we agreed on because i hadn't paid fully for the account yet.
HERE IS THE PROOF. first time doing this so i hope i'm doing it right.























i'm extremely upset about it and honestly, i really don't know if this guys intentions were this the whole time... he did claim to be the original owner of the account though. said he super heated all the way to 94 mage and that's why the smithing was level 72..
please tell me this is enough evidence.. he's been a member since 2008. why scam someone for 15m?? i messaged him on skype telling him the password had been changed about an hour ago, and got no reply back.
here are his vouches! i even vouched for him after i bought the account...
