The crafty bar stewards.
Last December I got my free BB upgrade from 100mb to 150mb.
This month my loyalty discount ended so at the end of May I phoned CS to sort something out and thought I had got the same deal as I had before.
But checking this months bill online I found I've been conned!
My
Free 50mb upgrade as been removed and I'm back down to 100mb.

I'm back on to CS in the morning.
