My student loans are supposed to be in deferment and my tax return was taken, what should I do? I was told that it could not be taken with a deferment.

I filed a Chapter 13 and was told that my Student loans were supposed to go into automatic deferment and my attorney faxed the company the documents informing them of the deferment, but they took my tax return anyways and I don't know to do about it.
