In a hostage situation what's the most likely thing I'd do?

I can do with or without but the hostage is 100% important to a secret mission. I paid ransom but no sign. The hostage sent a signal he's in trouble, unable to get to me for some reason but all avenues have proven fruitless. I have two weeks to get the hostage or move forward without him. Which was not the plan. And I like to stick to plans. Plus a promised.
