Prepaid Meter: Error 30

Since moving into our new home we had a problem of the Electricity prepaid meter not taking our vouchers. We logged several calls with the customer care center and what they normally do, they come and recharge it for us on the box outside the gate. But really? we cannot call them every time we need to recharge our electricity.

On the 20th of Jan 2018, we managed to log a call for EMM to come replace the prepaid meter. As of today we haven't heard from EMM. Refence Number: **********
