You bought them, you just haven't paid for them.
You can pay and they will be shipped to you.
Or you can refuse to pay and the sellers will likely open an Unpaid Item Dispute which will give you a Strike for each failed transaction. They then get their fees (about 20% of the amount you agreed to spend) back from eBay. Yes, it costs sellers money to sell here.
Most sellers have automatic Blocks against bidders with Strikes, so you will find it very hard to buy on eBay in future.
Or you can Contact the sellers and ask them for a Mutual Cancellation. They might agree, in the Spirit of Christmas.
