Legal analysis: it is not illegal for outsourcing companies to collect money at home, because it is natural to pay back debts. As long as the creditor's rights and debts are complete, the collector has not committed any illegal acts such as violent beating, detention, kidnapping, insulting threats, etc. Even if they report to the police, they will be considered as economic disputes and will only assist in handling them. I suggest you go to court to sue, and you won't detain or arrest collectors. When you borrow money, you must have signed an agreement. If you pay back the money on time as agreed, the company will not look for you.
Now you have violated the agreement and failed to repay the loan as stipulated. If someone comes to you, you should take the initiative to return the money to others. If you have no money at home, you should also know about it when you go out to borrow money. This is what you should do to save yourself more trouble in the future.
Legal basis: Article 673 of the Civil Code of People's Republic of China (PRC). If the borrower fails to use the loan according to the agreed purpose, the lender may stop issuing the loan, recover the loan in advance or terminate the contract.
