Why have I just had an email saying 'Home Phone - Order Cancelled'?

Why?

Hi,
We had to do this due to the missed appointment yesterday, everything will still be getting installed for you. I've managed to get an appointment for 6th Feb 1pm-6pm. Is this date any good for you?

Yes please Chris. Can you please confirm the appt?
The cancellation email was a bit much for me to take after yesterday's drama

Hi,
That's confirmed for the 6th 1pm-6pm, and I've plastered the house name you PM'd me all over the engineer notes!!
I'll keep an eye on it an make sure everything is OK, if you've got any questions in the mean-time let me know.

Thanks Chris.
