"Very Poor Service"

I was referred to the MSK in September. I received an appointment in January. I was asked to do a few things which were very painful and difficult so I was sent for xrays on my shoulders. I received a message in February saying they had my results and they would ring me on 18th March at a specific time. I teach so took time out of a lesson to take the call. It never came. I returned to my lesson. They did call but I missed it then due to my phone being on silent. I sent an email and tried to call them on my lunch break but after 30 minutes the call cuts off. No one answered. I received an initial response to my email saying I would need to make another appointment - how? They don't answer the phone! I have sent 3 more emails since, I have not received a response. I have spoken to my GP practice who say the results should be on my NHS app - they have not been uploaded. I still have no results. I have tried yet again today to ring and again after 30 minutes no response. Incredibly poor service - I will not be returning!
