I'm still pretty sceptical however because I think you will encounter a lot of cases that are difficult to diagnose just by looking at a persons data.
For example, the first ever case I dealt with was an autistic lady who had been scammed into buying broadband when she didn't have a computer. She only understood that she had signed up to the service when she started getting debt collection letters for not paying the bill. If I hadn't met her in person and only seen her data I probably would have just set up a repayment plan instead of writing to the ISP and challenging her liability for the debt which is what I actually did.
You'd be surprised how many odd cases like this pop up.
