Not the greatest of install experience
I've recently had BT out to install a new phone line and fibre, which in BT systems is two jobs (which I can just about accept).
Date and time were agreed and on the day I was the first appointment of the day. BT engineer does his bit and installs the line, but he can't tell me if / when the fibre will be installed so I have to wait until the end of the morning deadline (13:00) to discover that there was a problem with my fibre install and no engineer was coming.
BT engineer was trained to do fibre installs, so it wasn't a capability issue. He did say they have a new booking system, but their booking system does not help the customer at all.
