Generally I've seen this happen when you've contracted to do business in some form and the other side reneges on it in some way. Like you ordered something online and it never ships.
We were going to get a large water purifier from Costco. On the order of $6000. We paid, but we had 3 days to cancel. We found it for significantly cheaper the next day and cancelled. 3 months later Costco still hadn't reversed the charge, so we challenged it with the credit card company. Fixed in 24 hours.
Also, it's worth pointing out that when you challenge something successfully, it's effectively like it never happened. Interest gets rolled back and you can call to have late payments associated with that time period striken from your credit report.
On the flip side, I would never use a debit card. I've been told "your pin was used so it must have been you" when contesting small things there. Credit card have chips and some banks allow you to use pins.
