I doubt that this is really the case why they consider your request. They have tons of issue  here that still unresolved while they have a tainted reputation here which they don’t care to clean for so many years.

Probably your potential legal action makes them alarm and consider your request if you are not from Iran in reality. They sometimes do that to have a reason for seizing user funds. You can consider yourself lucky for recovering your funds from them. Withdraw it immediately.
