Am booked into hospital for a camera down my neck in the morning because doctor has concerns from a chat we had, was booked in at 8am, so whilst on the phone to ask about something to them and it seems they had changed my appointment and no one has bothered telling me.
I know it's not as important as a hospital appointment, but specsavers did this to me........within 30 minutes. In the shop, we arranged an appointment that suited me, which written down on a card (in case Opti thinks the old codger was mistaken). When I got home, there was an email in my inbox with an appointment an hour later.
