Consumer Redressal

Its almost 1.5 Years Now for dispute created due to Meter Reset after its Turn complete at 99999 readings in Oct 2019, then DHBVNL start to give me unexpected average bills without considering actual consumption coming in my meter, I paid 2 bills in this condition also that they confirm that we will rectify the issue and extra paid amount if any we will adjust in next bills, and also instruct me that not to pay further bills until they will resolve the issue, but due to covid lockdown they dont process the same for next few months, after lockdown removed they change the meter without informing me in July 2020, at that time my meter was running perfectly and consumption was approx. 4000+ , according to SDO they mentioned the reading on meter change slip they do official work but not marked that meter was running or not, after that they float a bill of Rs. 75000+ where as i already paid 2 bills of approx. 15000 after meter reset , and after generate the bill they send the lineman to remove the meter where as i was out of station, my Kids approached to SDO and he said that you need to pay the whole bill, then i ask that bill is inappropriate and i can pay only genuine amount, then he calculate according to his own wish and said that plz pay 37000 on the spot and we will adjust if any extra amount you paid in next bill, i do so because my home was without electricity, instead of resolving the complaint DHBVNL pressurize me, in and finally after payment of 37000 SDO ordered to place the meter back. rightnow i paid more then i consume and nowhere they are interested to resolve the complaint and sending the bills with arrears every time. on every bill cycle the disconnection team coming to my home and based on my personal call SDO doing the temporary arrangement to pay the actual consumption amount , but not resolving the issue permanently. he said every time need 10-15 days or 1 month , but several months gone, several online complaint made but closed at own without taking nay action... now i m thinking to approach the higher authorities or legal help needed to resolve this complaint. please advise me what to do ?
