<human>: Could you distill the essence of the text into 1-3 sentences?

My situation started back in 2006 when I got divorced from the ex and decided that I would be the good guy and basically agree to anything she asked for since I was the one leaving and felt guilty for not wanting to stay with her after being together for 16 years (12 married) with two kids.  This included the agreement to pay 1,200 a month in child support which I did every month on time and sometimes early in order to help her with unexpected expenses on her side due to moving, etc.

Everything was fine until 2008 when she thought that I was too happy and wasn't going to be coming back to her and now had a GF (I divorced my wife because of her anger issues and the fact that after 5 years of marriage counseling and three different therapists she refused to work on anything and the last therapist told us that I should leave her to her face) she decided to go to court and tell them that I hadn't been paying her.  This resulted in all the times that I gave her cash or money orders to go unreported to the tune of 12,000 (I'm an idiot I know).  I then agreed to have the support payment taken from me via auto debit from my bank account to avoid any further claims on her part of this and after paying the claimed 12K in arrears off I have been making all the payments each and every month this way since then and so imagine my surprise when I look up my credit score today to find that it is in the low 600's due to "late payments" in the last year for child support?!  How the holy heck is this possible and besides calling Child Services later today and speaking with someone who could give a rats ass about us bad dads how can I go about getting them to resolve this?
<bot>: – I have had child support payments removed automatically every month from my bank account for years only to find out that Child Services reported 5 late payments (90 days plus) last year and now my credit score took a big hit.
