Since there are 9 cards, there is a high probability that they are not from the same bank. According to what you said, the monthly consumption is 3,000 and the repayment is 3,000:

To put it simply, it is space for time. , let the repayment of 3,000 yuan be divided among 9 cards every month. Among the 9 cards, some have more arrears and some have less. I took out the part that came out and paid it back to the card with the second lowest balance. After paying off the card, I didn't use it temporarily. Since all the cards were reversed, I got another month of exemption for myself. During the interest period, continue with 3,000 for the second one, and add it once to the remaining 8 cards, and so on. Depending on your ability, you can pay off all the debts in 9 to 10 months without affecting your Life, and there will be no late fees due to exceeding the time limit, killing three birds with one stone.
