I regret buying this fridge at Makro

Hi I purchased a fridge at Marko ottery in 2018 i have the fridge for almost 2 and a half years and it stopped working . .I have made contact with the call centre regarding my fridge on the 23rd of September 2020 and have since spoken to.so many people and each time I hear different stories only to be told that my that my 2 year guarantee is finished which was fine but I.don't have a warrantee which was for 3years because I.did not register for it. First of all I.bought electrical appliances before and was never told that I had to register for a warrantee and even if that's the companies policy I wasnt informed by any of the staff or assistance that I need to register. . .I am sitting with a broken fridge for days waiting for assistance they always saying they will call me back and I end up waiting so long until I eventually call them. . .im really dissapointed and frustrated as I am getting absolute no feedback I dont feel its fair that I bought a new fridge not to long ago.and its already giving problems I am.planning on taking futher steps can someone please assist
