Defy Fridge

Good Day

my name is Rhulani Nukeri I'm currently in Pretoria, i bought a Defy Fridge in Centurion (Pretoria) in 2019 October, i had a problem last year August, i then contacted Game store due to Covid they have send someone to come and check it . My problem is that after they have fixed my Fridge works only for 3 or 2 weeks and according to the people who comes and check it, they keep telling me one thing that there's a linkage from inside and I was told that they are supposed to take and give me the new one. Because it is the 4th time they've been fixing it. please help me
