Having read all of these stories & having commented on this very subject in a different thread?
I notice one thread running through them all, that allmost with out exception no one has complained officially in writing, with a copy to their MP.
Take it from me it makes a world of difference, I used this to complain over my wifes appalling treatment in a modern hospital, & my son used it to coplain over mine much later.
Words mean nothing in one ear & out of the other, the written word ah thats different, register it get a signature, show you mean business.
Hand wringing will get you no where, if enough do it eventually it will alter, the system will never be perfect, but it will get better.
IF by some chance you get no result send it to your local paper, & then on to all the dailys, MPs do not like being asscosiated with that sort of publicity.
A word of warning double check your facts'
Go on try it.
