Ridiculous utility charges

We previously moved from Ikamva Mews due to safety concerns. We moved into They Hyperion 1st October, this complex was much safer and cheaper and also smaller. 14th December the day we received our bonuses we received an invoice, the two months prior to this we would wait on the owner to provide the invoice. Two weeks later we received an email stating that we should leave the gate open in order for the meter to be read. How is it possible to receive an invoice two weeks after payment and two weeks before the meter was read. Every month going forward our bill increased. The month of July we were charged R1800 for lights, there’s only one person home during the week as two of us are at the office. This month the agent Munei Mapfumo sent a text stating that electricity would be 3k. So this place is much smaller, it only has one bathroom and we previously came from a place with 2 bedrooms and two bathrooms. How is it possible to pay that much on electricity when most of us aren’t home 60/70% of the time. Please consider twice, maybe even thrice before considering moving into unit 2 at The Hyperion as you will be paying whatever the landlord sees fit. It’s ridiculous to pay 11k for such a small space. It makes no sense how can you go for cheaper and pay much more than a much bigger space. Don’t walk run!
