Paying 100 rand for electricity per day

<p>I have purchased a number of pre paid electricity tokens this month and each time i get a different a recharge value even though I am paying the same amount each time. I have paid 2000 rand for 20 days worth of electricity due to this.</p> <p>Surely if i purchase 300 rand of electricity and get 240 units the next time i purchase it should be the same? but no the last 2 purchases I have recieved 180 and then 50 for the same amount of 300 Rand.</p> <p>At the beginning of the month I made an 800 Rand purchase and only received 250 units this is horribly pathetic and the call center is useless in trying to resolve this!</p> <p>I have made 2 complaints and they report it as I have no electricity and somebody will come and look. This is not the case I have electricity but its costs way to much for what I am receiving and nobody ever comes to look at the issue.</p> <p>I then get forwarded to the customer care center which says it is not available to take my call due to system issues.</p> <p>I want to be credited with the correct amount of units that I have paid for which should be lasting 2 months and not 20days!</p>
