The bank has a strict review process for the promotion of credit card limit. Like those who claim that technology can help you increase the credit card limit, nine times out of ten, they are liars, either stealing concepts to defraud commissions or stealing funds from credit cards.

In addition, many intermediaries usually ask cardholders to provide credit card information, such as card number, expiration date and verification code. Not to mention whether credit card withdrawal is a scam. Do you dare to tell others that you don't know these important information about credit cards?

Therefore, it is better to believe it than not to believe it, especially in recent reports that some criminals cheat by increasing the credit card limit, and quite a few people are deceived.
