Can I sue Kentucky Child Support Services for child support fraud for not doing there job.

Additional information
She was also getting foodstamps for my child that wasn't living with her along with Medicaid and I also informed them of that and they did nothing. I provide full medical coverage for my daughter and have since the day she was born. I called them several times wrote letters. Send them proof and they did nothing but continue to take my $828 and give it to the mother who kept it for herself. So I paid alimony basically instead of child support to woman I was never married to. The child support service who is there to provide support for the child did nothing. My wife and I have 4 children together and we work hard for what we have. This woman committed welfare and food stamp fraud before and I notified them and they did nothing that time either. I called child protective services on her when I found out about my daughter living with the boyfriend, nothing happened.
