City robbing Us of electricity

<p>I purchased R200 pre paid electricity on 3 May 2017 ... 106.7 unit received.... Friday 5 May 2017 8 units left. How can the metre not be faulty and why should I pay R715 for them to check the metre box? They are robbing me from electricity and I must pay so they can tell me the box is faulty. was told to take the loss? Not a happy person right now .... </p>
