Unwanted Sales Calls

They call me and hang up, I call back and ask to be removed from the list, Misty (a floor supervisor, and not a friendly one at all) tells me that I have been added to the "Do Not Call List" this was three months ago and I still get a phone call and a hangup every single day from this company. Isnt that illegal? DO NOT SHOP HERE!! THEY ARE RUDE, UNHELPFUL AND INTRUSIVE! The worst part of all of this, Im not even the person they keep asking for, he does not own this phone number. This has been going on for almost 6 months! Anybody else having a problem with this company should report it HERE (complaintwire.org)
