Constant spam being received from Edgars

I think I have unsubscribed from the Edgars mailing list in excess of 50 times ****erally). Please remove me from your mailing lists as I no longer want to receive the spam emails from Edgars or any of its affiliate companies. I have never requested that I receive this nonsense either. Is it that hard to do? I don't even purchase anything from Edgars any longer because if you can't take care of a small customer request like the removal from a mailing list, then how would treat customers if you needed to return an item for instance? Not impressed.
