Constantly calls and leaves no message. Finally connected. Person advised calling from Alliance Home Security. We were chosen to receive a free wireless home security system if we agreed to put a sign in our yard advertising their service. I advised we were not interested and asked for our number to be placed on their do not call list. The person then stated we were no longer qualified for the offer to which I laughed and hung up. The company called again the next day. We repeated the previous conversation only this time the person simply hung up the phone on me. Have now blocked their number.
