Credit cards should be signed in person and bound to your mobile phone. Ask the credit card manager of Ping An Bank first, if he has handled it according to the personal data you gave him. If so, then the address is wrong and I didn't sign for it. Also, the courier company needs telephone authentication to send credit cards. Why was it an impostor without receiving a call? Please be clear, too Otherwise, you can call Ping An directly and cancel your credit card (it may not be activated yet! )
