If you go to your account settings, under Communications there is an option for Direct Mail, saying "Click here to opt out of direct mail marketing" (select it if you want to unsubscribe from direct mail). The second page of this link has you enter your home address and there is a drop down menu for the 2 digit id of the state you live in. The state list is wrong.
For example, if you look at the list of M's: MA, MO, ME, MH, MI, MN, MP, MS, MT. Not sure how you unsubscribe your address if you live in Maryland (MD).
This was the only venue I could find to report the issue (calling didn't really work out). Just trying to help.
