The last two days I've been getting calls from someone saying they're my credit card provider and asking me to answer various security questions. When I asked them Why, they couldn't answer, so naturally I put the phone down. It turns out they were from my credit card, but Owing to Data Retrieval Laws they couldn't tell me why they were calling! Surely this is daft? I'm supposed to give total strangers my details in this day and age? So an hour on the phone later, it's sorted when it could have been answered first time.
