A Debt on a meter can occur for several reasons;
The cost for the units on a newly installed meter is paid by a customer as a debt on their first recharge of the meter.
Migration of Previous Debt: If the property used an analog meter or an estimated billing system (Postpaid), and there was a debt before the installation of the prepaid meter, the debt on the estimated (Postpaid) billing account is migrated to the Prepaid meter account.
Penalties: If there was a bypass or illegal connection discovered in the house, the penalty charge is added as debt to the prepaid meter account.
Kindly visit the nearest electricity distribution company office to discuss your debt profile. As all meters are domiciled with them.
