The online loan was overdue, and my debt information was sent to my family and friends by the collection company, and I called them! Can I call the police?

If your family is harassed by collection agents simply because the online loan is overdue, and it is just text messages and phone calls, then it is of no use. This is just a civil dispute. Even if you report the crime to the police, the public security organs may not be involved in the investigation and may reject your request for reporting the crime as it is not within the scope of their business. Even if it intervenes, it will only serve as a warning to the collection agents so that they cannot collect through illegal activities. It is best to resolve the matter through the courts. Of course, the collection agents will not listen. Their goal is to succeed in collection. It would be best if they can achieve the purpose of repayment by harassing the borrower's relatives.
