Secondly, sending this information to you is a way to collect pressure. If you want to collect money at home, you need to sue through the court. If you have not received a court summons and the court has not made a judgment on it, then this statement is unreasonable. At least state organs such as the Public Prosecution Law will not directly participate. What you see is only the collection department designated by this company. They don't have any enforcement power. You can reasonably refuse their door.
Finally, I want to say that if you really owe money, you must pay it back, at least the principal. At present, the state prohibits violent collection, but protects reasonable and legal loans. You should protect yourself and not break the law. I wish you an early escape.
