Got a letter from the MS child support enforcement a month ago alleging that I owed a lot of money on child support. I would have to be negligent since the child support settlement was stipulated by the judge in OK to reach what they said. An attorney advised to return the letter, and so I did, and I have proof of payments. Today I got another letter from them saying that the department of human services has DETERMINED that I owe the amount stipulated in the first letter. But, how is that even possible if I’ve been making the payments since the very first month I was ordered to do so? i called, but got no help , especially when I said I had proof of payment and that it has been 2 years since the last time I saw my kid. They just said there's a case with that department. What can i do?
