Received a call from XXXX at XXXX on XXXX/XXXX/2015. The man on the phone kept asking for personal information, but when I asked him any questions he would only state that it was a personal business matter and could not provide any information until I verified my identity. I hung up on him without getting his name unfortunately. Today ( XXXX/XXXX/2015 ) I got another call from the same number. This time I made sure to get the woman 's name : " XXXX ''. She kept asking me to verify my information, and I kept refusing to verify any information until she told me the name of her company. She said it was " IC Systems ''. I asked for the company 's mailing address and she refused to provide it ( like actually refused! ) unless I would verify my identity. I could n't believe it and incredulously asked if she was really refusing to give me their address so I could send a cease and desist letter. At that point she said she was terminating the call and hung up.
