Jiangsu Rural Credit Cooperative's account opening certificate is overdue for 30 days?

I also received this message. I just went to the official WeChat account of Jiangsu Rural Credit Cooperative and asked about the customer service. The customer service said that it may have been handled by the owner of the previous mobile phone number, or the wrong number was recorded when handling it, and then the message was sent to our current mobile phone number after it expired. He said that it was either a business or an expiration notice, and there was no need to cancel the mobile phone number. Sorry, I typed so much, because I can't send pictures, otherwise I will send you screenshots directly.
