What a shame Barry, but this kind of bureaucratic bungling is typical of the behemoth that the NHS has become!
I say let Tesco or better still, Waitrose take over running the NHS.
You have been massively inconvenienced, which must be a worry at your age - even though you look great in your avatar 😉 - but what about the vacant theatre booking and highly-skilled surgeons and anaesthetists left kicking their heels for an hour or so as they didn’t have a patient?
You can be sure no one will get a bollocking for this incompetence, and the whole thing just goes rumbling on as usual.........
Hope you get tested soon.
Cheers, John.
