"Confusing letter from Barnstaple"

I'm getting in contact to give some feedback about a confusing letter I received from Barnstaple . It was 4 pages long and talked about receiving a video call. Whilst I was dialing the hospital to try and figure out what I needed to do, my land line and it was the doctor from the hospital who said they don't do video calls. This was confusing as the letter explicitly says “video call”.

I assumed he was phoning about an upcoming operation I needed on my right knee. I have had some Xrays for this. However, after some confusion, it transpires that he was calling to check on me after my operation for my left knee. He was calling to see how I was doing. My left knee is now very good and feels back to normal. I had the surgery during the pandemic an the service was brilliant. It was set up to help people like me who were waiting for knee operations I even had a private ambulance

What was confusing is that the paper work was so similar to last time that I thought this call would be about an upcoming operation and I was excited, thinking I was going to get the operation I needed on my right knee, but after speaking to the doctor. He told me I wasn't even on the waiting list yet.

I don’t see why the letter needed to be so confusing and 4 pages long. Could someone look at this? I am in no way criticising my care when I had my knew operation or the Doctor that called, they were truly wonderful.
