Lost check

I am a disabled veteran. I have lost my job due to DOGE cuts, and my unemployment has run out. I was able to secure help with my bill from my states veterans administration.  They sent a check to a address in Illinois, and the check has been lost. Please review my xfinity chats for specific details, but I need help finding this $600.00 check. I can not receive or make calls due to my phone being cut off. Please help. I need  my phone for emergencies,  due to my disability, and looking for a job.
