"Imaginary appointment"

I was told via NHS app. to attend an appointment at the local hospital to see a podiatrist at 10.30 am today. Feeling breathless and unwell (awaiting heart surgery) I went because my feet have been so painful and I thought this is one thing I can get sorted easily. The receptionist searched her computer in vain trying to confirm my appointment . Despite having my correct details she could not find any record. Two minutes before my appointment time and being unable to get a signal to get up the app to prove I should be there, she discovered the problem. Apparently what I was sent was not an actual appointment but a pre appointment date and time needed to confirm my addition to the waiting list. When I reach the top of the list a real appointment will be send to me by post. What an utter waste of my time with information I didn't need to know, never mind the waste of NHS resources and funds.
