oh I missed to put this on here.. sorry for this

is there anyway I could see my login history? after I get hacked, I just want to know when and where they loged in

I'm so confused what happened, but someone hacked my account and buy L$ and didn't use it (I don't know why) that person changed three times with 2500L$, 5000L$, 10000L$ so I want to get refund about this Because there's a lot of damage to reselling it. I know this is not that great money for someone but not for me so it will be appreciate if someone tell me how to refund.
