I had a bank transfer confiscated by Office of Foreign Assets Control. I think it was because the money (my rent) was going to someone with a foreign sounding name. I filled out all the paperwork to dispute it and was told they (a government agency) had no record of it. This was maybe eight years ago. I gave up on it because one month of rent wasn't worth the enormous hassle of fighting the government (to me, at that time). I changed how I made payments and moved on.

I've been criticized before for not fighting back. I had other struggles at the time. Leave me alone about that. I made the right call for myself.
