Others commenting about sanctions are correct. Chase did what was expected. Your experience was your fault.

Hopefully your account isn't frozen (happened once to a friend where they accidentally doodled a sanctioned country's name on the side of a check that had nothing to do with that country).

Search on something like "Syria refugee scam" and do your research before sending money. Always research a charity's actual use of money before giving to them. Especially if you can't find any records, they aren't transparent enough for any consideration.
