Tamil Nadu Electricity Board [TNEB] — energy theft

Address:

600004

I reported the issue to local office back in jan 2017 and send the email to on 07/01/2019 to [protected]@tnebnet.org ; [protected]@tnebnet.org

I am co-owner of the property 20/11 kesavaperumal sannathi street, mylapore, chennai 600004. I reside overseas and in my absence, there were lot of violation done by the co-owner c. Venkatesh, one such is an inappropriate use of domestic power to the unregistered shop, in which he does the dtp work too. I sent the clips with the light lid on the shop too for evidence. I don't see any action on this. Day by day his violations were increasing. He put up an unauthorized construction after the due stay order issued by the court in jan 2017. Before and till date using the domestic power for commercial use.
Could some one respond to my this energy theft, and do justice.
