Why is there a receipt under CCB's personal loans overdue dunning notice?

In order to ensure that the dunning notice can be received by the borrower in time, and indicate whether the borrower has received the notice. A receipt usually consists of two parts, one is a bank receipt, and the other is a borrower's receipt. When the borrower receives the dunning notice, it needs to sign the borrower's receipt and send it back to the bank. After receiving the receipt, the bank can confirm that the borrower has received the dunning notice. This practice can avoid the borrower's dispute over whether to receive the dunning notice, and remind the borrower to repay in time to avoid overdue repayment.
