My electricity bill for the month of June, 2018 is excessively high(net amount Rs 1380/-)comparing to the previous months.Our usage is nominal and normal like previous months but the bill amount is showing high usage(225 units).Our present meter reading is 4901 but previous meter reading is not showing in the bill.I think there are some mistakes in meter reading or computation or some other part.This is impossible for us consuming such a high amount o[censored]nits(225 units)in a month.Please look into the matter immediately and solve the issue as soon as possible otherwise I've to take some other step for my problem.
