Hi satyam7220,
I understand your concern regarding a possible wrongful charge of eBay fee. However, the best people to help you out with this would be the eBay Customer Support Helpdesk. If you have not done the same already, may I request you to report this issue to the Customer Support team by the following link?
Contact Us
Ask About Selling>>>Billing and Fees>>> Pick an appropriate item from 3rd Box.
I hope this helps!
Warm Regards,
Sapana
