Then it may be that the landlord adjusted the temporary quota before, and now it is due to restore the original fixed quota.
It is also possible that the bank actively lowered the fixed limit of your credit card (generally, the active reduction of the limit is related to the abnormal use of the card, such as often using the card to buy goods or cash out)
If the quota is occupied, the following may happen.
First, the existence of the card is not accounted for, but only caused by the transaction in the authorization stage (the transaction was successful, the bank frozen the quota, and the merchant did not ask the bank for money). (In this case, it is suggested that the landlord check in the unpaid bill two days later, because domestic transactions are recorded in 1-2 days. )
Second, is there any pre-authorization for card release? Generally, staying in a hotel and renting a car will involve pre-authorization, just like a deposit. When leaving the hotel or returning the car, the merchant will use this pre-authorization to settle the bill, and the refund will be less, so that the pre-authorization is completed. However, in some cases, payment was made by cash or other cards at the time of settlement, and the original pre-authorization was not revoked by the merchant staff, resulting in the quota being occupied. In this case, the domestic pre-authorization will be automatically lifted within 30 days, and the quota will be restored, so the landlord need not worry.
Third, the landlord made installment payment, and the unpaid installment amount occupied the credit card limit, but it was not shown in the balance because it was not officially recorded.
Fourth, there are several CCB credit cards in the name of the landlord, which is related to sharing a maximum amount, resulting in the amount being occupied.
Of course, it is also suggested that the landlord can inquire about the transactions entering the account through the detailed transactions of the bill. In terms of specific methods, it is suggested that the landlord can go to CCB official website-"Account Inquiry Service" on the left and select "Credit Card Inquiry". After entering the information as required, you can query the details of the last six months.
If you still can't confirm from the details why the amount owed has increased and why the amount has decreased, I suggest you call his home service hotline for feedback. At that time, the customer service can give you detailed answers in combination with your actual accounts.
