I called ChexSystems Security Freeze Dept on XXXX/XXXX/15. The CSR told me that she could n't help me because I had lost my PIN. I asked to speak to a supervisor and she told me no one there and would n't be in until Monday. She then hung up on me and so I called back and the same CSR answered the phone. I asked for her name and would n't give it to me. She hung up again and so I called back. this time she picked up the phone and just muted the line. While still on the line, I called from a different phone in the house and the CSR picked up.
