Punjab State Power Corporation [PSPCL] — erroneous billing

Address:

145001

Dear sir/madam,

I have paid all the electricity bills this year from january to march 2018 at my pathankot residence. The last bill issued on 3rd may 2018 is showing the calculations based on the old meter reading of 29/12/2017 and new meter reading as of 03/05/2018. Also in the bill issued in march 2018 is showing the old meter reading as on 29/12/2017 instead of the reading from previous bill issued in february 2018. I dont understand the billing details, how the calculations are done.
