Remedial measures for credit card reduction: repay credit card debts on time every period; try to repay in full; pay attention to the diversity of consumption; only use 80 of the credit limit every month; handle other matters at the issuing bank Financial business; spend lots and lots of money. As long as the user adopts the above method, the bank will quickly restore the credit card limit after the credit card limit is reduced. Credit card downgrades are generally caused by users using the card illegally. As long as there are no subsequent violations and a good credit history is maintained, the reduced amount can be restored.
