One of my Sky+ boxes was acting up and even though I got it working, there is no access to the pause and rewind functions or the planner and the bugger won't turn off. I called and got short shrift from their employee until I told him where he could ram the Sky Movies package and my two multi-room subscriptions.
He still tried to play hardball until I pointed out that my Sky+ boxes always go wonky whenever there is an update. It's all over the web and he couldn't deny it. I pointed out the problem between their hardware and software updates and how they seem to be very incompatible at times. I then threatened to involve a solicitor given that the update had wrecked one of my Sky+ boxes and Sky was culpable. He quickly offered a free engineer visit and a free HD box. Job done.
