I've met it, too. CITIC Credit Card Marketers pushed me to upgrade my Platinum Card. I specifically asked if there was any charge. He said there was no charge, but that day I found that if I didn't open the card, the platinum card would charge an annual fee of 2000 yuan. Then the telephone customer service complained that the credit card salesman didn't tell the user to charge the annual fee and the annual fee of 2000 yuan for not opening the card. The customer service immediately apologized and canceled the upgrade of the platinum card, and I didn't continue to complain.
