Yep, those listing fees are charged the second the vehicle goes live for sale, and they are non refundable, payable sale or no sale.
Contact Customer Services, but do so as close to 8 a.m. ( try now) , as there's more chance of Dublin answering, only speak to them, they can see a genuine error was made and hopefully, no guarantee, they will refund you one set of listing fee.
Contact them through a Call Back option here:

As said, only speak to Dublin, you'll hear if it's the dulcet tones from the Emerald Isles! 🤗
