Aqua Finance Inc FBO Connexus Credit Union Paid in Full…but still owe interest! Wausau Wisconsin

On 8/27/2015 we purchased a RainSoft water softening system.  On the installment credit agreement, the price was listed as $6450.  Our account number was X401891481.

We received an initial bill with a closing date of 9/11 and a payment due date of 10/8/2015.  We paid the "New Balance" of $6466.68 by check, not wanting to incur excessive interest, and the check was debited to our account on 9/29/2015.

We assumed the amount was paid in full, as this is the normal procedure for VISA, Mastercard, and other credit cards.  

On 10/20/2015 we received a notice stating:

Previous Balance - $6466.68    Payments and Credits - $6466.68    

Interest Charges  $16.72    New Balance 16.72

When we called to ask about this problem, we were informed that the interest was what accrued from the statement date until payment was received.  This, of course, is contrary to any other credit arrangement we have ever encountered.

As we were speaking, and reluctantly agreed to pay, we were informed that AS WE WERE SPEAKING, additional interest had accrued, and the new balance was now $16.77.  This was paid by phone via CREDIT CARD immediately.

The confirmation number for this was #88140.

This appears to be the worst kind of deceptive and predatory practice.  I will be writing to the Attorney General here in Kansas, giving full details, and copying Rainsoft, in case they are not aware of what their associated finance companies are doing.  

If I can find other Internet sites, I will be giving both Connexus and Aquasoft the worst possible review, and warning unsuspecting customers to stay far, far away.
