When does the VA pay out travel pay?

I went to a VR&E appointment/Interview March 13th, in Sacromento, CA. They had me fill-out the Travel Pay form. I was told I did not qualify for VocRehab but was told I would get travel pay. That was two weeks ago. I had to drive three hours to this appointment. I usually don't care about this sort of thing, but it cost me to go all the way down. I called the number provided and got no where. I got a person that transferred me to Mather Benefits, which was an automated voice and answering machine.
