Korean motor spares Edenvale- Van Riebeck rd

Purchased a Heater core for a Hyundai Atos from Korean motor spares edenvale, failed after just 8 months. Went back to them and they said there's nothing they can do and I have to buy a new one. Ridiculous. Didn't even try and help. Eventually purchased another one from a different supplier. Hope this lasts longer.

Thank you.
