Hisense's non existent after sales service.

I bought a Hisense fridge from Makro about four years ago. About a year and a half ago the water dispenser lever on the fridge broke. We got hold of Hisense and they said they don't have the part but will get back to us. Since then we have not heard back from them, nor can we reach them. We phone regularly but they don't answer their phones. They don't respond to emails. They have responded once to say that they can't help us. Their after sales service is shocking. And how are they unable to fix a fridge that is only 3 years old? Our ice dispenser also just packed up. We are trying to resolve that with them as well but no response. I would strongly advice anyone against buying anything that is Hisense.
