Hello reddit, need some help.

I have been trying to contact the Homeland Security Investigation (HSI) unit in New England (in Boston) by phone for the past 2 weeks to get information on property seized while they were executing a search warrant. 2 weeks ago, an agent told me that they needed to return my property after they took them a year ago because they found nothing on them. I had moved out of Massachusetts and am now residing in the Midwest, so they said they'll get back to me with an ETA on my stuff getting back to me, but they never called back.

I have called the number on their website, but the phone is down. I called the Department of Homeland Security and asked to be directed to the HSI unit in New England, but they either send me to the HSI tipline or another HSI unit that can't help me. There is no email, so I just sent an email to every homeland security email that is publicly available, but no one has responded back to me. The property they took is in excess of 10K and I'm at my wits end trying to see when they will send it back.

Any idea on what I should do?
