HP Printer Cartridge

I bought a HP printer last year October from Makro Centurion. The same time I bought extra ink cartridges. When I installed the ink cartridge last week it didn't want to work. I have returned the cartridge this week to the shop just to be informed that I have to contact HP direct. The cartridge only expire April 2016. The number they supp**** me for HP doesn't exist. I phoned other numbers that I found on the internet with no success. I feel that I bought the printer cartridge from Makro. Therefore they need to contact HP and sort it out. I either want a refund from Makro or to exchange the cartridge. I BOUGHT IT FROM MAKRO NOT HP.
