Here is what to do if ACS, C’V, comes knocking at your door:
A) Do not let them into your house. They cannot enter without your permission unless they show you a court warrant from a Judge. They generally will not have that. Letting them in is an invitation for them to mess your life up.
B) Do not tell them anything or talk to them. Be polite and advise them you are unable to speak to them. Close your door.
