Fixing Black Mold Issue

I am a single mom who is a homeowner. I live with my darling children and my pets. I work every single day at three different jobs to make ends meet. I recently became aware of a small leak going on behind my refrigerator in my kitchen. It looks like the leak has been going on for quite some time made a claim to my homeowners insurance, but they are denying my claim. I am forced to make out-of-pocket expenses. I am deeply concerned of the safety well-being of my children, and I and my pets living in a house with this magnitude of water damage and mold, I am swallowing my pride and asking for help anything is helpful towards fixing this problem and making it a safer environment for my family and I thank you for taking the time and God bless
