Why do they do this?

Just taken a telephone call to say my appointment has been cancelled to see the specialist next Wednesday. They are 'hoping' to rearrange the whole clinic session to 29th April.
It's a bit annoying because I've had my blood tests done last week and my HbA1c will cover a month when my readings were all over the place and now things are settled again, that month extra for bloods would have made a big difference to the 3 month average.
Why are appointments so regularly moved and cancelled these days? I understand if a doctor is ill him/herself on the day but when you get no reason,it's somewhat annoying.

Hi Dennis,
My name is Gill but I've been called Karen too (perhaps confusion with chocfish). Don't worry, I'll forgive you. :lol:
It's been one of those days.Aside the appointment cancellation, I had a bad hypo in the night (gawd knows why)and then since 7.00 a.m.I've been patiently trying to get Michael Jackson tickets. Given up now and refuse to pay over the odds for them on ebay.
Ho hum. Tomorrow is another day!

My husband has a theory. New to our area is a system whereby a few days before an appointment, patients get an automated call. Press this button to confirm name, that button etc. Well, last time I did not complete the call, as it asked me to key in my date of birth and as I did not know if the call was genuine, I phoned the hosptial the next day. It was a genuine call but I told the woman on the phone in these days of high identity fraud, there is no way I would ever tap in my date of birth to an automated message but my main reason for phoning was to confirm my attending the appointment, as I presumed that was the point of the automated message. She said there was no need as the automated message was just a reminder and the fact I didn't tap in info required would not affect my appointment. Well, this time, when I got the automated call, again I had no intention of tapping in date of birth and THIS is where hubby's therory comes in. He reckons because I didn't, it has cost me my appointment on Wednesday.I shall phone the hospital tomorrow to check but I find it unbelievable that this new system expects intelligent people to give out birth details willy-nilly on the phone.
