I bought something on JD.COM, but it hasn't been delivered for more than a month, but the verification code of the mobile phone number has been changed before. What should I do if I can't send it?

I bought something from JD.COM, but it hasn't been delivered for over a month. However, the previous mobile phone number changed the verification code, but it could not be sent out. The solution is as follows: You can open JD.COM, click My, and then click Settings in the upper right corner. Then click, the account is secure, then enter, and click to verify on the mobile phone, but the things bought in JD.COM have not been delivered yet, and the consumer has the right to initiate a "reminder" application at the front desk.
