The problem is, i don't know who is he/she, from where, and why he/she sent it..
in the memo, he/she just write, " hello mate, this is your gift".
What should i do now ?? he/she didn't even include her/his e-mail.
Do you think it's a good idea to send it back again, because i'm affraid the man/woman maybe send money to the wrong account ??
