I used to be like this. Because it was sent to you by registered mail, there was no phone number in the envelope, and the people in the post office were not so active. So it is too late. But don't wait all the time. You can take the short message received by your mobile phone (sent by the bank), write down your registered letter number and call your local post office to find out where the registered letter number is. Then the post office will give you a registered letter number according to your registered letter number (4 digits here) and where to pick it up. You need to bring your ID card. . . .

Generally, a registered letter will be sent to you by the post office, and then you can pick it up, but it will take a long time for someone to deliver it, depending on the service attitude of the post office. )
