I received Social Security disability same day as widow's benefits?

The day I went before the judge for my social security disability, I was awarded it, plus as my husband died 3 months before, I was awarded widow's benefits at same time. I was 57 at the time and my husband died at age 63. I get 2 checks of which one is under my SS# for $627 and another check from my husbands's (I guess this is my widow's benifits) for $285. My husband made much more than I ever made. It seems that I should be getting more from my husbands for my widow's benefits. I've called several times and always get the run around--usually hung up on as they transfer me to someone else. I also received disability from my work, which I was sent a lump sum, but had to return all but 400 of it back as they said they had overpaid me for the years I received it. This was from where I had worked. I sent them the check back. I really don't understand why my check would be higher than my widow's check. Does this seem right? I can not get any answers from the SS when I call and ask questions about it.
