Shirty service

I'm honestly disgusted by the service I have received from Liberty at the moment.<br> <br> I'm still faced with the problem that there has been nothing on email that explains as to why my account was debited twice on month of October 2015. I have called multiple times and only today, with the assistant from one of your personnel (Maria), I was able to understand the 'in advance' terminology<br> <br> The problem is that none of this information was disclosed to me by my current advisor during the policy changes which occurred on the month of between September and October 2015. Based on Maria's explanation, if the debit dates are on the 15th, 20th, 25th of every month, the customer has to pay in advance. What I fail to understand is that why should those customers suffer because of the fact that they get paid on those dates? Why should I pay in advance based on the simple fact that I get paid on the 15th? Surely Liberty, being such a huge company, should have accessed this and treated all customers with fairness by applying the same standard throughout the whole board?
