Unable to Login into a Server

Hello, Mojang.

I have came across the problem of unable to join a minecraft server with an error message saying I joined the server from a different location.  I do not have minecraft installed on any other device nor I gave out my account information.  I believe a hacker managed to hack my account and making me unable to play on my favorite minecraft server.

My minecraft username is 19DollarGiftCard.

Please fix this as soon as possible.
