Unbelievable but absolutely true sequel to my last post:
A few minutes ago I got a phone call from the hospital where I was due to have an echocardiogram yesterday morning (which I missed) offering me a new appointment this Saturday11th March, rather than on 27th April as they said yesterday. Of course I accepted very gratefully.
Even more amazing is the fact that the lady I spoke to had been trying to phone me, unsuccessfully, since yesterday. The reason she couldn't reach me was because my landline phone number was changed, against my wishes, when I changed telephone provider recently. (Don't get me started on that infernal story!) However the lady did not give up: she took the trouble to get in touch with my local GP's practice to verify my phone number and fortunately, I had told them just a couple of days ago about the new number. So the saintly NHS lady found me and all's well.
May blessings and cash rain down upon the blessed NHS.
