There was a discussion a few months back about their somewhat dodgy handling of cash advances (basically they'd made it impossible to ever stop paying interest unless you took special steps to get a 'settlement figure' and pay it off ¾tween= normal account periods).
Seems they figured out the error of their ways (or the FSA or the ombudsman kicked their butt) because they just refunded me all the 'finance charges' they'd caught me for.
