False Nc getting Registered for visiting Ex employer for Exit document

I had visited my ex employer for exit documents as he is not giving the same since long. i was made to sit for more than 2 hrs and then asked to leave due to unwillingness of concerned authority to meet for which i asked for Appropriate appointment but the same was not done and still getting forced to leave. due to this I called police & while having discussion with him suddenly the security personals started giving Rough pushes to get me out forcefully by getting physical. i have immediately visited police station & nc was recorded u/s 506 against one of the security but later i came to know NC was also filed against me u/s 323,504,506 which is absolutely false. this is only done to trap me so that they can stop me by going at the employer's premises. Kindly let me know how should i get the False NC Revoked and File an FIR complaint against all 6-8 security personnel's getting physical
