Another situation is that banks can be eliminated, but communication is more difficult. I have seen credit cards (obviously harmless, for example, the company's collective salary card is a credit card, and the parties did not know it at the time). The annual fee was overdue, and the bad information was revoked by the bank through consultation.
If the landlord really wants to eliminate bad records, he can try, but he is not optimistic. Sometimes banks will issue non-malicious debt certificates.
I hope my answer can help the landlord!
