City Power's new Prepaid Meter boxes

I would like to give them no stars. They changed my pre-paid meter box to the new model. From the date of installation it has not worked properly. Everytime we have to load units we must log a call to get a technician out to come and test and input the units at the box on the wall, not on the meter box. We were told this is because the new meter boxes are not compatible with solar hybrid systems. We lost out on the remaining units that were on the old box, but in good faith we believed it was a glitch which would work its way out of the system. It is now the 2nd time and we have had to do the same call logging procedure again. I would not recommend anyone replace their old meter boxes until the systems are improved. DONT even try following up with the call centre agents. They are just rude and unhelpful..
