This just happened to me today. I was a bit confused as i am currently subscribed to a magazine. When i was asked to verify my birthday my gut said something was wrong. I told the woman i wasn't comfortable giving out my info over the phone and before i could hang up she assured me she had my info. Yikes. Told me i was going to be billed to my card ending in ####. She had my last four correct and mailing address. I hung up.
