Question

I need to know how I go about possibly suing an Independent License Social Worker? The problem I am having is my husband and his ex-wife were court order to see this person because of his 13 year old and now she has charged my credit card thousand of dollars (which I have now put a stop payment on & I am also disputing the charges) and is refusing to give us a detail bill of all charges made to my credit card. I have emails stating she won’t send a bill w/out my husband coming into her office and then turns around and states my husband & I are lying and we already have copies of the bill. This person has also threatened to give my husband a bad review to the courts because we have told her she is not professional and refusing to do her job. I am also started to get Migraines again and I am stressed out because of this person action and it is putting a strain on my marriage
