There are no listing fees for Private sellers unless you added any optional listing upgrades such as a Reserve? These are non refundable, sale or no sale and charged the second the item goes on sale.
If you added any of the following there will be a charge you must pay ,as eBay will chase you for it, and be aware , they do use debt collectors.
Reserves: 4% of the set reserve ( maximum £150 per item)
Subtitles: £2
Listing in 2 categories: 35p
Gallery Plus: £2.50 ( free for clothes and shoes)
Listings with duration 1 - 3 days 35p
As a tip, for any future listings, before clicking on the final List Item With Displayed Fees button, glance just above it, it should read £0.00 Listing Fee.
If there is a fee amount listed there, you have selected an upgrade, and if you wish, it gives you time to scroll up and remove the payable upgrade.
The one thing unfair on removing the ' fake' item, is the way that message is written. The claim the item is 'not authentic' is not explaining the true issue here.
High brand items are protected by Vero Regulations and policies. It was the brand owner, not eBay who asked for the removal of your item.
There are so many fakes of high brand items and impossible to check authenticty for online items, even receipts can be faked, I know, my work took me to the Far East for decades , and fake receipts made there, are impossible to tell from the real deal.
You may well see identical items listed, the site is massive over 7 billion + listings on at any one time, so not possible to check every listing, and some slip the net and become listed.
Your item has been reported do not relist it, you would face serious selling restrictions.
You can read about Vero's policies from a link at the bottom of most eBay pages.
