RAC ignore your marketing opt-outs

Is this a legal fail in any way? Quotes from a letter received from the RAC today:

You’ve asked us not to send you any information about the other products and services RAC could offer you.

Indeed I did.

Normally we wouldn’t, but we’ve made some important changes at RAC that could benefit you. So, as a valued member, we wanted to make sure you were aware of them.

Translation: Because we actually don’t give a fuck about you, we’ll ignore your stated instructions and tell you anyway.

Did they even look at the chance this would piss off more people than would buy from them? Idiots.
