We are on a do not call list and this recorded call advertising carpet/ upholstery cleaning comes in as "ASOC." From your website, this company appears to have a "history" of violating do not class registrants. Reverse directories show the # as unlisted. No surprise, there. I have filed an online complaint with the FTC do not call website.
