The Salvation Army USA complaint: Rude and Unprofessional Employee

My friend’s mail has been sent back to sender by an employee at the Salvation Army. This employee, on several occasions, has yelled at my friend and asked him to, GET THE F OUT! My friend has been waiting to receive crucial remaining mail (He now has a PO Box) from DMV registration card, his IRS W2, and his Kaiser medical card. This mail was being sent to the Immanuel House AFTER his change of address with the DMV. He is picking up the last of his mail. My friend has raised concern regarding one particular employee by the name of, Owen. Owen has continuously yelled at my friend and used foul language. I have heard him on the other end of the call while my friend has talked to me on his cell phone. I was astonished to hear the way Owen demoralized and humiliated my friend. I wrote an Email to: Dan Guhl (manager at the Immanuel House) only to find out that he became upset and asked my friend, Why did you have your friend email me??? That same day, my friend walked inside to see if there was remaining mail for him, Owen then told him, GET THE F OUT OF HERE. I DECIDE WHETHER YOU GET YOUR MAIL OR SEND IT BACK!!!!! It is apparent that Dan did not have any interest in resolving my initial complaintconcern and only became disturbed at the fact that I had emailed him. I still have all email threads of the complaint. I wish for this matter to get resolved. To know that the Salvation Army is treating the homeless so shamelessly poor is humiliating.
