what was the complaint? why did you not let them in? I know if cps came to my home I would gladly give them a tour, even if the house was a little messy (usually is) and if I keep chooks in tha garage, I have nothing to hide, and I am not saying you do but wouldnt letting them in have made the whole thing end? Now cps probably believes the complaintent and not you, and I cant say I blame them. I would question what was goingon in a home as well if I got a call and then was not allowed in.
