today, I also received this call, 755-3298888, saying that I can upgrade my CITIC credit card to a platinum card directly. When the platinum card is swiped, I can withdraw the amount at any time, and there is no upper limit. I remember that the maximum amount of a black card is 1W, so why is there no upper limit? I asked what the fee is, the annual fee is 2,, and they all have all my information. I said, let's do it. I don't worry after hanging up. The other party first admitted that this number is CITIC's outbound number. Secondly, the other party did apply for a platinum card for me. However, the amount adjustment is not just because you are a platinum card. It needs to be adjusted according to your usage. My card doesn't cost a few dollars a year. Originally, if it can be upgraded to more than 1W, it would be cost-effective for me to use it for turnover. Unexpectedly, it is impossible to adjust the amount, and my annual fee of 2 will be deducted. If it is not pitted, I will directly ask the bank to cancel it. When people encounter similar situations, ignore them.
