You have not provided sufficient information to enable experienced buyers and sellers to give you clear and precise answer.
Lack of information means we are guessing at the circumstances surrounding your issue and advice may not be appropriate.
In my view following information would be helpful.
Did you open a return case on eBay?
What kind of case did you open, Item not as described or did you select another reason?
Who paid for the return label, You or Seller?
Did you return/ Post the item before expiry of deadline date?
Do you have a tracking number for the item you returned?
Does tracking show item delivered to sellers address?
