Cancel online banking after receiving SMS.

Take my ID card and go to CCB to check. This happened to me: an office of CCB informed me that I could get another credit card because I applied for online banking, because I was rated as a quality customer during this period. I wonder-I haven't done online banking, how can this happen? So I suspected that it was a fraudulent phone call, so I asked the other party to provide my personal information, and people got it right. I am even more strange-I happened to be in the hospital during that time, how could I apply for online banking? Later, I went to the bank to inquire, and the savings window said that there was no online banking for me, so I simply set up one. After a while, the mobile phone received a short message: You have cancelled the online banking service. Just after I put my mobile phone back, my family called: How did you cancel my online banking? I am angry and laughing: how do you handle your online banking with my ID card? It turned out that my family was very confused when she ran online banking: the information is both hers and mine!

Another possibility is that the bank made a mistake in processing and entered the wrong ID number. So you'd better go to the bank yourself.
