How do you know you were not heard? Because no miracle occurred? Because no one came to "save" you? Perhaps in His infinite wisdom, God knew the important thing was for you to dig yourself out of the hole you were in. Apparently he was right . . .
Just a thought.
Edit: In regards to punishments being heaped upon God's Chosen People, all I can say is that from those to whom much is given, much is expected.
