Here's my problem with this. I/we (DH and I) knowingly had PPI twice, about 10-12 years ago.
The first time, I understood what it was, agreed to it, and then cancelled after a few months. It was either Egg or Lloyds TSB, a credit card, I can't completely remember, but I do remember knowing about it and agreeing to it.
The second time, DH took it out without me realising on a joint loan we took out. I realised after a month or two and we cancelled it.
Both times, we knew what we were doing. We worked in a volatile industry, and thought the protection was useful, but in the end couldn't afford it.
More recently we even had mortgage repayment protection insurance, and we claimed from that policy. Not very much, but even so. It was something we purchased knowingly.
So why should we get compensation? We knew what we were buying, did other people really not know? Really?
