Order Received - Order Canceled

Over the past 36 hours I have attempted to place an online order totaling $3046.02 not once, not twice, but SIX times. All of the cancellation emails from IKEA state that I need to call the card issuer (it's an IKEA Projekt Card issued by Comenity Bank/Bread Financial). I call the Bank to find out what's wrong and the rep says,"Everything is fine with your account, you have a zero balance and plenty of available credit to cover the almost $3100 transaction." Great. Love that for me. I then call IKEA's customer service and they have no idea what's going on and keep telling me to call the bank.
