Help with Father Passing & DFAS

Hello – My Father was a marine and passed away. I have been trying to get in contact with DFAS to stop his retirement pay and to see if he signed up for survivor benefits.

I have been cycling between three different numbers I have for them and I keep getting "You have reached the DFAS automated information center. We are having technical difficulties processing your call. please try again later." and then it hangs up. This has been happening for three days.

I don't know what to do.

thanks
