NO REPLY FROM MANAGER-REMOVAL FROM MAILING LIST

I HAVE BEEN STRUGGLING WITH RCS FOR QUITE SOME TIME NOW. I WOULD LIKE TWO NUMBERS REMOVED FROM YOUR MAILING LIST AS YOUR OPT-OUT DOES NOT SEEM TO WORK. I SPOKE TO SEAN AND HE HAD ASSURED ME THAT HE WOULD REMOVE THEM OFF THEIR DATABASE EVEN THOUGH AT FIRST THEY SAID THAT IT CANNOT BE DONE. I WAS TOLD THAT THEY NEED AN ID# TO ACCESS AN ACCOUNT TO REMOVE THE NUMBERS BUT THE PROBLEM IS THERE ARE NO ACCOUNTS OPEN. PLEASE CONTACT ME IMMEDIATELY SO THAT I CAN SPEAK TO SOMEONE HIGHER THAN SEAN. THIS NEEDS TO BE RESOLVED AS SOON AS POSSIBLE.
