Social Security Questions? Ask a Social Security Expert
Unfortunately, if your request for waiver of overpayment has been denied, there is nothing else you can do. Your Congressional Delegation regrettably cannot help you with this one. Social Security Administration can get the overpayment through deduction from your benefits. So, regrettably, the deductions will continue to be made until the overpayment is paid off.
I am sorry that I do not have better news for you.
