Item arrived defective and i spent a week trying to submit a return request butit would not submit. Possibly because the device I use cannot attach photos. So i submit a "remorse" request and sent the seller a message saying it's defective because i don't want item onsold to someone else. 

Seller is offering partial refund but says i have to close the case before he can issue refund.

I've never had to return an item before so I'm not sure if that's correct and his feedback ( which stupidly I didn't check until after i experienced issues) says if you close the case they ghost you and you don't get anything!

Advice please
