Violent collection, crazy harassment, what phone call to complain?

In the case of family members being harassed, the parties can report the case directly by reporting complaints or calling the police. If there is an emergency, such as the loan company sending someone to collect money at home, using abusive, threatening, intimidating, painting and other methods to take excessive action against the borrower's family, then you can immediately call the police and immediately stop the collection personnel's behavior. Anyway, you need to keep the evidence.
