So, I just received a letter today, sent out 4/22 from dfas. It says

“1 NPT DEBT IS DUE TO PAYMENTS RECEIVED AFTER YOU ENTERED A NO PAY STATUS DUE TO SEPARATION AS OF 08/01/2022.

THESE PAYMENTS ARE AS FOLLOWS: END OF

MONTH PAYMENT OF $1988.97 DATED 08/31/2022.

1 NRP THE DEBT IS DUE TO A

MID MONTH PAYMENT OF $1989.44, DATED 08/15/2022. THIS PAYMENT WAS FOR 15 DAYS. DUE TO YOUR DATE OF SEPARATION, YOU WERE ONLY ENTITLED TO 01 DAYS.”

It says I owe 1,678.95$ & have 30 days to pay.

No idea what this means, any advice? Call? Argue? Just pay?
