Need Help with Starcraft Account

Hi, as a quick question is anyone aware of a way for someone to retrieve a very old Starcraft Account?
Roughly 3-4 years ago I switched to a new computer and had slowly drifted away from the game, but recently I managed to set up this old computer and found my old starcraft game. When I tried logging in it failed and I'm not sure what I can do. My old account name was TheOtherW and it doesn't seem to work anymore. My friend told me to make a new one but its been ages since I've seen my disc. Is there a way to contact Blizzard and reclaim my account? Thanks again for your time guys.
