who's number

Robocall offering free wireless alarm system. I pressed 1 and was connected to a hard to understand woman (ESL) who tried to get info from me. I gave her made up name and phone number & refused to give email address. She transferred me to "Josh" who gave me the sales pitch for the "free" system with a $43.99 monthly monitoring charge. I asked him who monitors, he replied, "Monitronics." I asked who does the install, he said, "Our installers." When I pressed for the name of the company, he replied, "Alliance." I got his call back number: 855-495-1918.
