PRE-PAID ELECTRICITY METER PROBLEM

I am a ratepayer of EMM and purchase electricity by using the EMM's pre-paid system. About a year ago my pre-paid electricity meter started displaying an error message (\-30-\") whenever I wanted to \"load\" electricity. I reported the problem to the EMM's electricity department who sent out an Electrician to \"load\" my electricity at the meter box outside my property. About 2 months later the meter started to PERMANENTLY display the error message. Since then I cannot load electricity nor can I view how many electricity units I still have available. Every time I purchase electricity I must contact the EMM's electricity department to send an Electrician to come and \"load\" the electricity at the meter box outside my property. I have reported the problem numerous times, without success. Surely it is extremely counter-productive to have to send an Electrician out just to \"load\" electricity at my property every time? I am at wits end ... can you please help?"
