Is the arrival notification message true?

It must be fake. These so-called visiting short messages are forged by these third-party collectors, and they will cause you psychological pressure by various means. They say the purpose of coming to the door is to intimidate you, because you are afraid of the other person coming to the door. The more you are afraid, the more he will seize this point, creating psychological pressure for you, and making you actively negotiate with him about repayment. If you insist on not asking, they have nothing to do with you.
