Complaint: Meter reading being wrongly taken for few months and causing slab change and high bill for subsequent months. Example. my avaerage consumption is 80-90 units and average bill is 250-300 rupees, but for last month reading was taken as 45 units
and all the remaining units got added to current month and slab changed and current bill is drastically increased to more than 600. I noticed this pattern several times and complianed but its still being repeated. Please check attached bill, resolve the issue and change meter if needed as my meter is still manual one.
