Seller telling me they “deserve to die” because I said their product didn’t work.

TLDR: I bought a printer and the Bluetooth features only work for phones, not computers, weird, so I said it wasn’t advertised as such I would like to return it.

Seller messaged me back saying “this is my negligence I deserved to die” because of my bad experience… I don’t want their shop taken down or anything, but idk if I should report it because you can’t just message people violent thoughts like that!

Should I report it? Or even finish my return lol?
