We didn't get a solicitor in the end, my OHs insurance only covered her getting sued not going after twats in suits for being dodgy. We just kept up pressure on the ombudsman and GTEQ (pretty much ignoring Atlas, they are proven liars so why bother?), and when we did get calls off Atlas made sure they knew we were recording them. They act very differently when recorded, they flat out refused to talk to me even if my OH said it was OK and then hung up. The call recorder I have on my phone always records every call, so you don't have to remember to activate it.
I did also post on GTEQs facebook page, I posted on a few other pages owned by the David Plum too and generally called them scamming bastards. Once blocked from the pages I had a few mates do the same, just for a laugh.
I will say through all this talktalk were great, I'd have no reservations in recommending them to anybody after all the help they've been. True they couldn't have stopped the transferals, but they could have easily charged us for breaking contract (numerous times!) and were happy to waive everything for us to stay with them.
