My daughter's child care fee is automatically garnished from my wages. My daughter is, as of August 2013, attending a free preK program (same owner of daycare). My local child support office advised me in order to start a modification, I need a letter from the former daycare provider stating she is no longer enrolled. The provider, who is the owner of the privately held center, refuses to fill out any paperwork even though I legally have joint custody. She is unwilling because she is related to my child's mother. She even refused to complete it when the CSS rep came on-site. What are my options?
