Enormous billing showing usage of 271 units which is unbelievable as i was not at home during the entirs day. Electronic gadgets only used after 6pm. Pl check my consumption for bill of march. How is it possible that 271unit of electriticity has been consumed in an empty flat when none is there to consume it???
