Good Morning, My customer id number is [protected] and my consumer id number is [protected]. I wanted to inform that my bill amount for the month of April has come in negative. Can you please check and advise as to why it is in negative. Request you to please check and advise if there is any issue in the bill or in the meter reading so that the correct bill payment can be made.
