Co-op Bank security questions

I've just called them to request a new card. In the queue I had to type in the whole account number and sort code. The first operator then asked me for my full name and the and the expiry date and last 6 digits of the card number. She then ordered the card, which took around five minutes. Then she told me that I had insufficient security on my account. I had to give my full name again, then full address, then make up a four digit code that I would remember.

I was then passed to another operator, who wanted a memorable name I had given previously. She then asked me for the name of my last school, entered the information and passed me to a third operator. She asked me for a four digit code which could be or not be the one I had just given, the name of my last school, my memorable name from before, my place of birth, then the name of my first school!

At this point I lost my rag a bit and said it seemed more like data theft than bank security. There have never been any issues on the account and they hadn't contacted me about security before. I appreciate that they have to keep my money safe but does anyone else find this a bit ridiculous?
