Not using your name? What are you talking about? The issue is whether or not they are using your benefits in your best interests.
As long as you have shelter, use of utilities, food and clothing and your basic needs are being met then you can assume that your benefits are not being misused. Misuse of benefits is like when a child of an elderly man used her father's benefits for herself and stopped paying his mortgage. He lost his house because of her. She, BTW, ended up in prison.
Your payee is not accountable to you for their use of your SS benefits; they are accountable to SS and must file a yearly accounting. Benefits are suspended if the payee fails to file the accounting.
I was a SS claims rep for 32 yrs.
