Mental harresment and threatening for transfer

I am a banker and in 2017 posted in a branch after the previous manager put under suspension of doing some fradujent loans ... I was told to rectify all the loans .. as there is a compliance certificate we have to submit I wrote everything that I found wrong doings in the branch... I was than put under pressure that no need to esclate the loans and all wrong doing . I denied as I have to tell every wrong doing in the branch and the frauds of loans tune up to 6 crore ... And in 2019 all have been reported to cbi... Since 2017 they have made my working in the branch very difficult .always taking to me rude way ..threatening to destroy my carreer and threatening to transfer me knaya Kumari and deep South ... Always treating me unfairly in the branch ...not letting me submit my all fact finding to cbi... Putting unnecessary work pressure on me... Making my life difficult in the branch I want to go leagl with all these seniors and I have all supporting documents with me.. I also want to get the stay order of my transfer as it is not correct .. Please guide me how I should go abt it
