"Demoralising waste of time"

Back pain and intermittent numbness both legs, loss of bladder control saw physio via video during covid. I was given very basic exercises that did nothing. Told I would receive follow-up for non-specific back pain. No appt received. Re-referred 1 year later for same issues, had telephone appt given exercises again that I could not do. Waited for follow-up, eventually I get message asking if I still need appt? Finally saw lady physio 2 days ago who insisted I had been seen physically before because she had the notes. She asked what my expectations were and I said I wanted to know if it was ok to do exercise without risking damage and was there any imaging needed? She said we dont do that unless its something that can be fixed by surgery? So I said then you can discharge me if you are not able to do anything else. The physio did not understand what I said, she was busy talking down to me after I had explained I was already very depressed that day. Then I get letter saying I am discharged because I refused examination because they would not mri! This whole situation is purely wasting your time, patronising you, making you feel like you are imposing on them. Whole team could do with training on how to communicate with people who are worried, have legitimate distrust of service, have been abandoned on a waiting list for years and then get offered nothing. My GP told me she cannot refer me for any imaging unless these people say so! When did some physio become responsible for my health when they know nothing about my med hist? Dreadful, should not have contract renewed. Fleecing NHS for money for a good run around before discharging you anyway.
