Just got emails saying WE had canceled 3 out of our 4 bookings for Friday (all 4 now, after another email arrived).

We effing did NOT. This is frigging ridiculous.
ETA: I think I managed to get us all rebooked for Friday but we have to go to 2 different pharmacies - hubs and I will go at 10 am to the original pharmacy we booked at, daughter & son go just before lunch to a different pharmacy. They better not cancel this set.
