Jodhpur Vidyut Vitran Nigam Limited [JDVVNL] — My electricity meter is jumped and billing is wrongly done

My last month electricity bill has come as 17764 rs . But for past 3 years my bill never crosses 1500 rs. I don't know what is wrong with the JDVVNL people, no is ready to answer for the bill. And as of me I feel so bad that even after being a government officials they have no response or responsibility to answer . Is this how you loot from others and when we come to question you said to pay what is printed ?? This happens only in india especially in rajasthan
