If the landlord can't handle the installment due to insufficient quota, it is suggested that the following methods can be adopted to solve this problem:
First, apply for increasing the quota;
Second, for the part with insufficient quota, you need to apply manually to complete the installment transaction by depositing the corresponding amount of money.
Third, the landlord can pay part of the money to the merchant in cash or other ways to reduce the amount of installment payment, which needs to be discussed with the merchant.
When the amount reaches the installment amount, you can apply for installment. The landlord can call the bank customer service hotline. I hope my answer can help the landlord!
