I tried to preorder something that was 77.99. They took one payment of 17.49 but i get this is message

This is a temporary authorization to make sure your payment method will cover the payment. Your payment method will be charged when Pay in 4 completes your order.

  
So did my order go through? How long does this message appear for before my order go through. Also I panicked and did this twice...So I have two payments of 17.49 taken out of my bank.

I have never had any issues with the pay in 4 before. Can someone help
