Although the circumstances were different, the only time in my life that I really wanted to beat a woman like a baby seal was when we went thru the process of getting named as pre-adoption guardians for our adopted son. The CPS woman was a condescending, egotistical, judgmental, lying POS and a general road block to our gaining the guardianship. She was the supervisor of the office we had to deal with.
I ended up hiring an attorney to deal with CPS as I had enough and my head was ready to explode. Luckily, a judge agreed with our attorney, our son that wanted to live with us and gave the CPS woman a lecture.
I later found out that a few years before, she had a run in with our son's former foster parents and somehow it was our son's fault so she was determined that he would go to a group home and not be placed with us.

I got pissed off again just typing the above and it happened in '89. Good luck with your issue. I will never trust anyone, without verification, from that outfit again but at my age, it's unlikley I will have to deal with them.
