Cancelled order still hanging around

Customer service cancelled a order for me early Monday morning due to a weird glitch in their system. It's still hanging around on my dashboard as being "on hold". Has anybody had an experience with this? How long does it take to clear? I've gotten multiple answers from Customer Service. 24 hours... then 48 hours... then 4-5 days. I can't get a straight answer. They didn't send an email saying it was cancelled. Just verbal confirmation from several agents.
