The credit card of Bank of Communications has not been paid back for two years, and the amount is 18000, so it cannot be repaid temporarily.
Bank of Communications has two shared lines, and the lines are shared, but the repayment must go through that card, so it needs to be returned to that card. The amount used by this card cannot be repaid in another card. Other banks are basically the same. I mind if you cancel one according to your actual situation.
