Is this creepy, should I change my user name, and how the heck do you delete a myspace account?

I used to be a member of another Q&A site years ago. I answered a question there about bioidentical hormones probably around 2008.
Today I got a phone call (on my cell) from a guy who is desperate to help his wife who is suffering the same way I was before I got the bioidenticals.
I’m a little freaked out. He was able to take my name there and somehow connect it to my myspace account. He them found my last name and city and ended up finding the name if our business. Our business answering machine gives my cell.
This guy was innocent enough but it sort of creeps me out! I need to cancel the MySpace account that I never use but I can’t figure out how to do it.
I hope none of you are creepers but just that someone can find my last name, my city of residence and my cell phone just by googling is unsettling.
