Held hostage by an agent

I bought a property at the above complex and the agent (3%.com) and the seller never told me about the system that the complex use to buy electricity.

The system is so bad and unfair. You can only biy electricity from the selection estate agent. You deposit money into they account and they only check they account from 13h00 then they generate a token for you and send it. You are charged R20 each time you buy, if it's an "emergency" you are charged R50. They closed from Friday 5pm if am not mistaken till Monday. Which means if you run out of electricity on Saturday you will have to stay in the dark till Monday and on Monday you will have to wait till 13h00 form them to start checking they account if your deposit have reflected in they account, otherwise you not getting any token.

I recently bought a token on a Thursday and was told if you didn't do an immediate clear deposit it will take a day or 2 for the money to appear in they account. Never got any token till Monday later close to 5pm and the reason was i had made a mistake on my reference. My kids had to stay without proper meals on Sunday and Monday because we could not afford to cook. My wife and kids had to bath with cold water on Monday because we could not switch on the geyser.

When i questioned this system on the complex support WhatsApp group i was told by one tenant 'you cant come here and want to change the system to make it easy for yourself'

To make matters worse, the agent we use to buy electricity does not only close on weekends they also close from the 15th of December till January if am not mistaken. Which means by the 15th you must have brought electricity for December and January otherwise you will be in the dark. What happens to those thatget paid on the 18th or 25th or monthend?

We have all this technology where we can buy electricity from literally anywhere but we can't. I don't even know what agreement the complex have with this agent and who owen this agent. Imagine buying airtime from MTN or Vodacom via your bank and you are charged extra than you are told you will receive your airtime after 8 hours or when your money reflect in our account.

Please if there's anyone out there who can help with this or give direction because we are held hostage buy this system and the agent told us that there is nothing we can do and referred us to the complex caretake who will do absolutely nothing.
