Uttar Haryana Bijli Vitran Nigam Limited - SUNDRY CHARGES ADDED WITHOUT ANY NOTICE

I am the consumer of UHBVN and the account no. S**MU******M. The Uttar Haryana Bijli Vitran Nigam Limited have added the un-necessary charges in terms of sundry charges of amount **** /-, before addition of charges no any notice received from UHBN side. When I have called to ask about clarification of charges on UHBN toll-free no. ***********, no positive feedback received from there. Without any justification they told me to pay the amount also they told me that the charges are applied once in the year. I have checked my previous years bills, there is no charges of such amount. All the bills were payed by me on time. My electricity meter is working properly.
