It's frightening isn't it? I had a call yesterday from a company I deal with online. The first thing he did was call me by my first name, which got my back up for a start. Who am I, his best friend? He then said that he needed to verify that I was the account holder, so asked me for the first line of my address. I refused to give it, and pointed out that he called me, at which point he stated "Well, we can't give you any information unless we can verify who you are." Bloody cheek! I told him I never asked him to call, and haven't asked for any information, and if there's a problem with my account, send a letter. He started to waffle on, so I told him I was very busy, and hung up.
