when our office was closed, and remaining staff transferred to homeworking, it was decided to install separate phone/broadband lines for them. I argued against the office managers decision of BT, and was given an opportunity to contact Virgin. Which I did, but they didn't reply, so probably no great loss there.
BT managed to cock up every single install for 5 people. When it was all sorted (2 months after the contract date) the office manager asked why I had been so anti-BT, and couldn't understand my answer ... "I've used them."
Seriously, my wife and I can't recall a single time we've had a BT service from install to moving which hasn't been blighted with some spectacular incompetence.
The worrying thing is, having been private for the better part of 40 years, all the systematic incompetence from the 1970s era must be gone now. So where is this new generation of muppetry coming from ?
