Tipping the MSEB off

Someone in a huge commercial setting has a set kiya hua meter and I am related to them and they have recently wronged me, I need to know how to go about tipping the MSEB off about their scammy meters, they’re stealing electricity from the state. And they’ve wronged one of the few people that knows abt it. Would love inputs on how to go about this ! Bahahahahahaha (evil laugh)
