Why no filters for my Samsung Fridge

I bought a Samsung fridge at Dions that cost me R28000.00.<br> I need a new water filter<br> I am expected to drive to the Samsung service centre to get a new filter.<br> Why does Dion not stock Samsung filters.<br> They are very willing to take my money but not willing to give a service.<br> Is it because they do not make enough money on it or because they do not sell enough of it.<br> Guys it is called service, if you are willing to sell something make sure you can service to poor idiot who supports you.
