TEP ITO investigation

Dear experts, I sent TEP recently, today relevant IT officer called me to meet him to get the work done. I wonder what he asks me in - person and worried about whether he asks me to withdraw it as my FIL is bit influential there. Can any one explained me what would happen there. What if he says orally my FIL has not paid and close the compliant. I know that FIL has not paid any thing and made false 498 complaint. How can I demand for the TEP number to my complaint? Immediate help or suggestions are appreciated Thanks
