I did NOT sign up

I am now receiving unsolicited emails from Edgars. At the very bottom of the promotional email it says that I am receiving this email because I signed up for it. NONSENSE. Although I have an Edgars card which is about 10 years old and I never use it, I most definitely did not sign up to receive advertising material from Edgars now. When I go to 'unsubscribe' it gives me some complicated method asking for account number, cell numbers etc. When I enter my email address it says that there is an error and I must call your Call Centre. I do not see why I must be inconvenienced because you *******ly email me. Take my email address off your data list immediately and stop acting *******ly sending UNSOLICITED emails..
