This is gejandrababu from alcherry village and in having eh 3 phase meter in my good down... As I paid 7770 rs on 08/07/2020 after last payment of 2270 rs on 25/10/18. There is much difference in that tariff . I failed to pay last two month of EB payment.. now I am ready to pay the payment.. but in EB office issued me the bill some amount of 11000 to 13000 ( not clearly mentioned).
But the usage is more lesser..
Only 2 lights and 1 fan ... That to in evening.
So I'm requesting you to take action on this issue and make correction in bill payment.
Thank you
