Midcity (Kwela) Prepaid Electricity... Worst service EVER!!

It has been more than 3 months that Prepaid Electricity customers are unable to obtain their Prepaid Balance. After changing their prepaid system without notification they developed an app where one can view your prepaid balance, the app worked for a month... Now there is absolutely no way to check your prepaid balance, NO notification when I buy prepaid electricity. I keep getting sms's stating that one can obtain your prepaid balance by sms'ing BALANCE and your prepaid number to 37823. I've send hundreds of sms's, but haven't receive any balance updates. Customer service is non existent! I've phoned, I've emailed, but nobody can give an indication of when this will be fixed. It is absolutely RIDICULOUS!!! Imagine if a cellphone provider tells their prepaid customers there is no way to obtain their balance. I'm really FED UP! Unfortunately I can't chance my service provider as I stay in a complex who decided to use these IDIOTS!
