Repeat of issue previously sorted

I wrote a report on the 11th of Jan 2016 about how the credit card division just took money out of my account to pay for the overdue card, when I already had an agreement of paying a certain amount every month.<br> <br> They did refund me the money 3 days after my report which I am very happy about, but now again the same thing happened.<br> <br> I just don't understand this.
