Some banks , maybe most, you can sign up online and set up email or text alerts for deposits or debits. Then no need to call asking for a balance..
You would get an instant message alerting of any deposit.

I was wondering about any VA benefits/wounded warrior, etc also.
I don't know how that system works/overlaps with a SSDI case.

If you are in dire finances SSI may be applicable.

Many have the same questions about the "system", some reasons it is slow.... it is bogged down with ageing baby boomers, the slow economy makes it harder for many with some slight disability to find jobs that fit their needs... All claims need to be checked out so the system isn't paying out for unqualified claims.
