Gangster practices.

Gangster practices.
I received my bill for my Gas 2 months after submitting my meter readings.
Now a few weeks later I get a correction, my rates turned out to be incorrect.
However, I had a permanent contract.
Or could it be because I change energy supplier?
I am going to do everything I can to make this company, which has been taken over by Japanese, in the spotlight everywhere.
So I will not stop here.
