social security dissability have been ripping me off albany, Oregon

I was just informed by my wife that the Federal Government has been ripping me off for over a year on my dissability, It's hard enough that they only pay what they pay but to take more than i owe, is just criminal. I make 784.00 a month, then they take medicare from my check at 99.90 amonth, then i have a court order for back child support of 50.00 a month, which leaves a bal of 635.00 a month, but the trick here is they only deposit 622.00 a month. so then weres the rest of my money. 13.00 a month for the last year and a half,

well i made two calls to SSD and the first call I made on Dec 6 2012 the woman gave me no info about where my money was, and hung up on me. I called back two minutes later and spoke to another woman, who said she would check on the matter. So as I was waiting she hung up as well. If this is what I put that that a&&#@)^ in office for is not going to happen. Our government is a rippoff and there is no way i will ever vote democrat again. They have done nothing for this country but put us in more debt. And as for the republican party they can go suk my mule......
