Card-operated electricity box in rented apartment
So I was just scrolling on facebook and I saw a post of someone complaining that they have a card-operated electricity box in their rented apartment, and it is overcharging them for electricity. The comments all said that it's illegal here.
Now I also have an electricity box, I pay the owner and they give me the card. Now with excessive AC use in the summer heat €100 credit can get to zero in less than a month. My apartment is a studio btw, so quite small. I wasn't aware that these are illegal, and as the owners and the apartment are very nice, I wasn't questioning it until now. But I start to feel like I'm probably overspending on electricity, because 100 in less than a month feels insane, even considering the AC.
What can I do? I don't want to have bad blood with the owners, and I definitely don't want to move to somewhere else, because I like living here. But money is money. Shall I report it? Or should I just suck it up, because I would have to move if I report?
