furious customer

I've always heard people say they being ********** by this municipality, I'm experiencing it for myself where I've paid more on my account but told that I used the wrong ref. Now they telling me the was a letter delivered at my place on the 08/01/2019 when I was home the whole day didn't receive the warning letter but got the letter for disconnecting my electricity. Now being charged a reconnection fee of which I've paid more on my account but now owe an amount I have never being charged before. They rip people off and it has become a norm.
