I emailed EA using the link on http://www.tbrb-freedlc.com/hmv/ explaining the situation, and they replied very quickly. I was impressed with them, unfortunately I think they misunderstood as they sent me the codes to register for the free songs- which I have no need for. In addition to this they sent me the American Gamestop codes and not the UK HMV codes.
I've replied and explained the situation, and like I say their previous email was very pleasant and helpful there was just a misunderstanding. It does feel like UK PS3 owners are being messed about a bit considering we had to wait over a week extra for Abbey Road and it seems have not received any of our promised free songs yet.
