Dear Sir, Based on the facts you have shared, the allegations under Sections 135(1) and 135(1A) of the Electricity Act, 2003 appear to involve important factual and legal issues. The validity of the notice and the assessment will depend on the inspection records, meter data, technical evidence, and the procedure followed by the electricity company. I recommend that you visit my office with the notice, assessment order, inspection report (if any), electricity bills, and all other relevant documents. After examining the complete record, I will explain your legal rights in detail and advise you on the most appropriate course of action, including the available remedies to challenge the notice and assessment, if warranted.
meet some local lawyer and give the reply to that notice first
Check with the internal manager about this issue. And show ur payment bills to them and if you have any doubt on anyone doing so you can raise questions in the society if it's a common meter. Give more details to get more clarity.
