The only way to sell items on eBay is through a Sold listing. You can't just directly send an invoice if there isn't already a transaction with the buyer. If he wants to purchase the item, he can purchase it through your listing. Or you can listen to your mom and end the relist auction, too.
You have no obligation to any member who has not actually purchased your item. It's OK to ignore the demands of a sore loser. Personally as an experienced seller I would not want to deal with a buyer who has demonstrated that they have a short fuse when something goes wrong, especially if they were purchasing an item made of glass. So I think you should end the new listing too nd hand over the bottles to mom.
