Samsung's Horrible After Sale Service

I got a new set of U-Flex headphones from Samsung. The headphones where faulty and could not charged. i subsequently handed it in to be either repaired or replaced. the feedback i got from Samsung is that the headphones could not be repaired and they don't have stock to replace them.

So after more than a month has passed, i don't have a set of headphones and Samsung is not getting back to me, can this not be compared to theft on their side?

Their products are generally great, but it would seem their after sale service is so bad it is making me reconsider buying any of their products in the future.
