TNB shall be the one stopping people from stealing instead they allow electricity stealing for months or years then come and ask for payment … so they deliberately want to profit from that … their system would have detected irregular consumptions …

they bypass smart meter, how to detect like that? 

You may not understand the concept of how they steal electricity. The reason why it is called “stealing” because the cable didnt even pass thru the meter. Unlike the typical meter tampering and limit electricity passing thru the meter, they now perform total bypass.

The way i see it, owner of property shall not be liable, this is as if a thief steals goldbar from goldsmith and store in the unit, so goldsmith cannot put owner of property responsible of stealing the goldbar.
