The idea
While I agree that I do not want my private data to get into the wrong hands the majority of institutions and organisations that I have had to converse with by phone seem to use this as an excuse for being totally unhelpful. It is terrible when you cannot help your teenage, young adult children to sort out a problem because someone will not speak to you. Also, I have been married for nearly 30 years and cannot get Utility companies to put Mr & Mrs on the bill and then if I have to ring they will not speak to Mrs because it is Mr on the account! Rediculous!
Why is it important?
There needs to be some trust and the ability for families to help out young and older members alike.
