I am facing Harrasment by a Private electric Company . Kindly help..

I have electricity connection from SNDL a private electric company.My electricity bill from 200 units shot up to 2000 units per month .I had to make a payment of about Rs 90,000 but I made a payment of Rs 50,000 under protest on 31/08/2015. On 29/09/2015 they temporarily disconnected my electricity without notice or informing me , And from that date they remarked on every bill that the meter is inaccessible , although they themselves took and put the picture of the meter every month on the bill which proved the meter to be accessible. On 06/10 /2017 they removed the meter without notice or informing me. Now I am receiving calls daily from their vigilance office that their is theft of electricity . They did not give me any notice or informed me about theft or done any panchnama and didn't took signatures of any of my neighbours after passing of so manny days. Can they take any action now. I am thinking of going against them in consumer forum .
