Deducting installment before due date

<p>Time and again Atlas debits my account anywhere from the 22nd. </p> <p>How can you deduct money 3 days before the due date and I end up with almost no money in my account because I only receive money on the 25th as stipulated in my contract. </p> <p>I have spoken to the branch about this before and it still happens! </p>
