Every month usually I have received my consumption bill amount approximately Rs. 1000 to 1100 only, but last month I have received bill for 93488, suddenly it has came like that. When I asked the concern person, he said the tariff is LM61(Building work usage) that’s why, but as per my usage and environment it supposed to be LA1A(HOME USAGE). Building work also was not done for last 13 month, then how could the concern department has raised the bill for 93488.Suddenly they are saying this is Building work usage charge from[protected] to till date without any intimation to me. As per rule and instruction, they should inform me 18 month before right? Why should I pay this much of amount? People who are all in the department not giving proper explanation and not even respect also I am from lower middle class family, I can’t bear this much of amount. Please take necessary action and do the needful.
