I will. Common credit cards are valid for 3 to 5 years. The validity period is printed on the front of the credit card, and the cardholder can take out the credit card for observation. If you don't want to continue using the credit card after receiving it, and it is not activated, you'd better cancel it. When applying for card refund, you only need to call the customer service hotline of the bank where the credit card belongs with your mobile phone to apply for card refund.
