.. as it - er - wasn't. After an hour of driving through north london traffic, we arrive at the appointed time and place to find the clinic closed. An hour and a half later when we finally get hold of babybond we get no apology, just "oh there was a "mix-up" and for some reason we weren't told the clinic wasn't open yet and had been booked to go to the Norbury clinic. No disrespect to Norbury, but we had to look it up in the A to Z and its the opposite side of London to us!
So a completely wasted morning, for which I had arranged childcare. They "kindly" offered to take our £120 and scan us on 1st June (!) - or as my DH said, we could just book with an organisation that seems remotely f-ing competent.
