I received a text message from ICBC today, asking for an explanation.

Hello, I suggest you first go to the local People's Bank of China to get your personal credit report to see if a scammer has used your ID card to apply for a credit card. If so, take timely measures; The second is that he means that you have not used the card for a while, so you have lowered your credit limit. To ensure the safety of your card, you can ask ICBC customer service to confirm whether ICBC will issue a refund if the card has not been used for half a year. Send this text message to the customer. By the way, I want to ask if you have applied for a card at ICBC. I hope it can help you. If you don’t understand, you can ask me.
