Mobile provider does everything wrong:
“At this point I was pretty sure this was a social engineering attack, so I started to quiz her about why she needed the information. She said it was for a “security check”. I told her I was uncomfortable giving out information like this to a cold caller over the phone and she said it was nothing to worry about because it was all covered by “the data protection act”.
I said that I would rather conduct my business in an Orange shop, and she told me that she would have to put a mark on my record that I had failed a security check. I interpreted this as a threat, which convinced me that the call was an attempted con. I asked for her name and ended the call.”
