In reply to a post by BatBoy:

Engineer no-shows are quite common with BT installs, I believe because their ordering system doesn't cope with Openreach needing to change dates etc.

I had a BT engineer call me yesterday to do an installation that I'd been told by Zen on Wednesday couldn't go ahead because Openreach hadn't worked out how to remove a DACS on the line. Nobody had mentioned anything about a DACS to him, let alone a change of date.

For a company whose business is communication, BT doesn't seem very good at it.
