"Lack of communication between staff"

I have never had a problem with this hospital before everything was OK until March the 13th 2021 when I was given an appointment for 8am in the morning prior to testing positive for covid in February the 11th and after my isolation I was asked to go do another covid test on March the 1st but came back inconclusive then they decided i will be treated as a covid patient which I had no problem with on my appointment day in gate 13 Endoscopy unit they had no idea I had covid they did all checks BP and blood sugar and booked in, once they found out in my paperwork I was told to leave immediately and I tried to explain I wasn't actually positive but treated as positive and once she understood she told me to sit on the plastic chair which they can easily clean I felt like I was dirty after that the doctor comes and tells me I was booked in the wrong unit therefore they will not be doing the procedure I couldn't understand how one can book someone in the wrong unit and it cost me £120 to book a taxi to be there as I was not allowed to drive after Endoscopy and that error cost me as if I am the one who booked myself on it I am furious the service was rubbish they have no customer care and clearly not educated enough when it comes to covid worst day ever.
