For example, I used a CCB credit card with a credit line of 2,000 yuan, and I swiped it twice: 1 1,000 yuan and 900 yuan (1 1,000 yuan has been credited and will be displayed in the balance, while 900 yuan's is not credited, so it will not be displayed in the balance, but it will occupy the line), so my available line = credit line-balance-. Then I can only brush 100 yuan at most.
However, you can increase the available quota by adjusting the temporary quota. Adjustment method of CCB's temporary credit line: adjust the amount in the last four digits of CCTE# CardNo. (for example, the original credit line is 2000, and now it needs to be adjusted to 1000, that is, the last four digits of CCTE# Card No.3000), and the approval result will be immediately fed back.
I hope I can help the landlord!
