One collects SSI for years. A SS worker tells the recipient that they are eligible for SSDI eight years ago and should have been put on it. They switched the person over to SSDI. SSI then notifies the person that they now owe for back payments totalling $29,000 due to an error the person was not responsible for and had no control over. The person had been told that, being that SSDI was $20/mo more, they would be getting compensated for the past eight years they had not been getting it. However, now the person is being told they owe SSI $29,000 and that the SSDI will not be paying that money, which is what they should have been paying all along. So now the person is left holding the bag.
What remedies does this person have? Who should they go to for help?
