If it is overdue for 5 days, the storage fee of 65438 yuan +0 will be charged every day.

2. The e-mail cabinet looks a bit like a locker in a supermarket, but the difference is that it has more computers operated by touch screens, and the storage compartments are also divided into three types: large, medium and small. When the customer is temporarily unable to receive the mail in person, the postman will contact the customer and put the mail into the email address designated by the customer. After the postman closes the cupboard door, the computer will automatically send a text message to the user. The content of the short message includes the verification code, the contact information of the person in charge of the mailbox cabinet and other information.
