Got to say...
.. that I do feel a bit sorry for the staff, but I wouldn't use BT Engage for anything. The only time that I had anything to do with them, the people that I was talking to had no idea of what was going on and the more that I talked to them, the less impressed I became with their abilities. It's no good outsourcing work if it ends making more work for your own staff; and quite clearly, we would have been in that situation.
(When ever I hear about someone doing the rounds of the troops, I can't help but remember Young Mr Grace - "You've all done very well".)
