No respect for due dates

<p>I have a credit card with Nedbank and for the past few months they have decided to change the due date of my payment from the 25th of every month to the 23rd. I don't get statements, so I have no idea what I owe them or what the monthly installment on the card is. I have been trying to keep it up to date by paying amounts that I think I owe them. I have been getting numerous calls where they inform me that I'm in arrears and every time I would explain this to them, but the consultants are rude and don't listen to what I actually discuss with them. They don't care what my story is, they just want to make a point by telling me that I'm in arrears. I'm now tired of this!</p>
