State Bank Of India [SBI] — sbi officials seems to behind the fraud, they may be passing on customer information to criminals.

Hello everyone
I am just wondering how are the criminals getting information about customers of sbi without their knowledge. Yesterday (14th august 2019) from one # criminal saying that he is calling from head office of sbi gurgaon, mob no:[protected]. I remember the same guy called me around six months back, which clearly means that whatever complaints we raise to sbi customer care doesn't get attended to and the reason for the same may be that, sbi officials themselves may be passing on our important pieces of information to criminals like him. I told that guy that i am tracing your phone number and put you in jail, and he said you # off and come faster to my office and i will wait for you. The only way we can help ourselves from sbi credit card fraud is by stopping all transactions with sbi and open account in other banks.
If sbi officials themselves are criminals who are passing on our information like this we dont have any other option other than this. If sbi is really concerned about this, they themselves would have taken up the matter with cyber cell and they can easily nab these criminals. Question here is "the biggest bank in india has # sitting in top positions?"
