I am STILL waiting for my Social Security Back Pay!

I cannot believe this!
I have been waiting for months for this back pay!
I have been getting my monthly disability now for three months and still I haven't received my back pay!
It is crazy how Gov't offices can be so different!
When I got my disability pay from the VA, the day I got the letter I went checked my account and it was already there!
Yet with the Social Security, I have waited in vain!
Well the 12th makes it an entire full month since I contacted them and they had said a full month and I should receive it. So if by the 12th, and I'm not holding my breath, it isn't here, then I am going to be calling and expecting answers!
