Offered me a position then ghosted me - Civil Investigator PAE Employee Review

Disorganized and lacks communication. I was offered a position with this organization, signed the offer letter and had a brief conversing HR. I went to get the drug test and signed paperwork for clearance. So after waiting 2 months I called HR left a message plus sent email. After no response after I day I went into my candidate portal and say that my status was “Not selected”. I think it’s really unprofessional that no one in HR informed me as to this change or why. I would steer clear of any company with such lack of communication.
