I'd keep calling your contact person. If it's been more than a week , I'd call the main SSA number and explain that you are not getting a call back from your contact person.

I know how frustrating it can be......I've been trying to get SSA to understand that I am no longer collecting WC (which capped out my family benefit) so they should be paying my kids $900 a month. I've been trying to work it out for a year now.........bureaucracy never moves quickly.....
