Hi cazna-2007,
Go to the Account Tab on your My eBay page, click on Seller Account and see exactly what the charges are for, by viewing "All account activity".
It could be you have somehow subscribed to something which carries monthly charges and will need to unsubscribe.
If you still require help after seeing what the charges are for, please come back and explain what the recurring payments are.
Don't go around saying the world owes you a living. The world owes you nothing. It was here first.
Mark Twain
