Why do you always receive short messages in the wrong format from the bank recently?

Hello. The mobile phone number you are using now has been used by others before. After someone changed their new mobile phone number, they didn't cancel it. The official business hall recycles and renumbers this mobile phone number and sells it to you. So you will receive some information from people who have used this number before. You don't have to mind. You can also use your spare time to consult in the business hall. The business hall will handle it properly. After the problem is solved, you won't receive any information from the previous person.
