Dear Sir or Madam:

I am in receipt of your e-mail communication of August 10, 2020. It was apparently related to a different FOIA request than mine. I, Phil Mocek, placed my request with your agency on October 20, 2017. The PDF attached to your message, however, is addressed to a Joseph Cox, and pertains to a request he reportedly placed on July 5, 2019.

Please advise.

Phil Mocek
