Of course they don't want you to get involved and call animal control; animal neglect and abuse is a crime. That's like a bank robber asking you not to call 911! And consent has nothing to do with it, if you see a crime you can report it and leave the investigation up to the authorities.
Now, I can tell you that most animal control folks don't know much about reptiles. They can handle dogs, cats, and livestock just fine, but reptiles and birds aren't their area of expertise because they don't come across those types of animals very often. That's why I suggested contacting a rescue to see what they recommend.
