Complaint Review: ashton-drake galleries / Bradford Exchange

This company has repeatedly sent unwanted mail to my post office box. I have tried to contact them by phone, they still send it. I have tried email but there are no email addresses for them -- the advertised email Customerservice@ashtondrake.com does not work. Their contact form stops and tells me my zip code must be 6 (that's right six) characters - a blatant attempt at avoiding contact by any means. These people added my address to their mailing list with in a 10 day period - NOW they tell I have to put up with their unwanted mail until THEY decide not to send it any more.
