Just got a call from 0 10-95558. I was connected to customer service. It is a boy. Is this the customer service representative of CITIC Bank? I feel a little tongue-tied. I feel a little Fujian or Guangdong accent. At that time, I wanted to know how the customer service staff of the bank couldn't even speak Mandarin clearly. ) Ask me if I have a credit card from CITIC Bank and if I use it well. I said nothing, no problem, and then the man's "customer service staff" said, in view of your good use and good reputation, how much can I help you increase the credit limit of this card (in fact, my card was recently released and has not been used until today). I said yes, what should I do, and then the customer service went on to say that he would check the information with me and let me report the card number of the credit card, so that the customer service would know me. The card number I quoted has four mantissas, and he asked me to quote it all. I think this is wrong. Could it be a liar? Then I said, forget it. My credit line is sufficient (the credit line of the card that just came down is 15000, which has not been used so far). Then he said he was sure he didn't want it. Then he said yes and hung up. At this moment, I am almost sure that this is a liar. Then I called the bank and asked if there was such a thing. Fortunately, I didn't fall for it and share it with you. I hope I will be careful not to fall for it.
