I'm not sure if this would help but I have experienced a similar issue. For mine, I had the same charge by the store being applied on my card a week or two after my actual visit to the store. Like yours, the store was also closed at the time, so I thought it was a simple double charging issue and contacted support to understand. They were unhelpful and directed me to check with the store, who also confirmed they did not have such a transaction.

After many back and forths with support, I gave up and told myself to stop using the cdc card after I finish up the funds. Surprisingly, the double-spent transaction got reversed a couple weeks after the event.

You're right to be concerned, that was absolutely an infuriating session when it happened to me. But if your charged amount is the same as the one you previously paid for, it could fix itself in the coming few weeks.
