[Solved] Unremovable Heat Radiators: Overcharged Despite Zero Usage - Seeking Advice on Actions & Solutions

Hello.
I've lived in a new building for a year. I have unremovable heat radiators on the radiators. Ok, nice. Till today. I received a settlement invoice. I pay the rent for the heating and allocate the allocators once a year. The bad luck was that for the first year no one lived here, the apartment was closed and radiators turned off at zero. Unfortunately, the allocators had it somewhere and calculated the heating. I have to pay PLN 682 for radiators turned to zero. Well, such anger in me grew that it was close to me that I took the hammer ax and dismantled them quickly. But since there were always good professionals here, I would like to ask for advice. Should I take a hammer and dismantle it or an ax and go to the manager for an interview?
I just feel robbed!

You must check the regulations (I do not know if the cooperative or the community) how heat is accounted for. For example, it is also the case that all the heat consumed per block is divided so that 60% for shared heating, i.e. those rooms that are unmetered and 40% divided into allocators. I used to have the opposite (60% for divisors and 40% for common ones).

Hello. Show what is your divisor?

Despite the thermostatic valves turned off, as the room temperature in winter will drop to 8 degrees, the valves on the radiators open automatically so that the radiators do not freeze. Maybe you left the window ajar during the winter.

The divisors I have at home look like this:

The windows were definitely closed.

Submit a settlement. How many impulses have these allocators received? Maybe the thermostatic valves are now to be replaced?
I have the same in a little used apartment and if the thermostatic valves are turned off, it doesn't give any impulses ...

For example, I can give you my accounts for 2017. I only had 86 impulses on three divisors. The flat is normally used, the block is insulated in rooms around 22-24 degrees. In the annual settlement, about 10 PLN was charged for these impulses and I paid over 350 PLN for the remaining part. As I wrote before, we have a 60 to 40% split
In the picture I show my divisor.

It turns out that the problem concerned one divisor. In the radiator turned out to be a faulty valve that despite turning to zero and still let water. I don't know if the developer will refund me for the crazy heating. Case pending, valve replaced free of charge. Tracking it was achieved by listening close to the valve. There was a slight noise.
