Cape Town's electricity rates are the same for pre-paid and post-paid. There's no hassle to pre-paid either because customers can buy online.
Curious to know how they did that. I know you can mess with the counter in the meter by tampering with your AC wave.I heard that some prepaid meters in general can be set to charge you a more expensive price depending on your suburb. This lady went to complain to her local municipality saying she is paying too much on electricity it was discovered upon opening the meter they set her meter on a higher rate.
