"Very disappointing experience"

I am in pain due to a torn cartilage. It is affecting my mobility. I am lucky to have private medical care but always need a GP to sign one form prior to private treatment. Too hard that for Valens Brockwell Surgery - even when your GP is a few yards away in the building! After a day waiting for the the GP to sign the form I visited the surgery. My letter had not been opened and I was sent packing being told over and over again that it takes 5-7 days to have documents signed. There was no negotiation. How poor. No ‘extra mile’ here.
