Dear sir/madam,
Last month reading is not taken in my house scno.[protected]. When i visited eb office on[protected] and informed the bill collector about reading not taken. He informed me that he would come on3-10-18 to my house for taking reading.
After i left the office he has sent message for bill payment stating consumption 300units bill amount rs 530./-
My sc readings are as follows:
16.07.[protected].09.18. -7443
