"Not seeing medical staff"

I had surgery recently. I had previously seen a Dr in January and was listed for surgery. I complained in June about waiting List times. I received an appointment for August for pre assessment and noticed I was under a different consultant.  I had my surgery recently. A registrar consented me in the morning, but that was the only Dr I saw that day. I have no idea who did my surgery and I saw no medical staff after the procedure. For all I know it was a porter who did the surgery!
