If the landlord still needs to use it, on the one hand, it is recommended to pay the arrears before using it. On the other hand, you can try to apply for a temporary quota of CCB. There are several specific application methods, and the landlord can choose one that suits him.
First, the telephone self-service voice
Second, online banking-credit card-credit card quota adjustment.
Third, SMS adjustment, the landlord uses the mobile phone number reserved in his home system to edit the SMS "the amount to be adjusted is the last four digits of CCTE# card number" to 95533. (For example, the landlord now has a fixed quota of 10000 and wants to adjust it to a temporary quota of 15000 with a card number of 8888, then edit the short message "ccte # 8888 # 15000". ) If you apply by SMS, the default time for the temporary quota is 2 months.
If the landlord has other questions, you can ask.
