Game store bad service

Previously I’ve bought a double loader, clipper x2, fridge x3, laptop, blender, tv x2 and other things. I’ve never brought the stuff back for repairs, except for this Hisense tv I bought in November last year. Came Dec last year it showed blue lines. Sent it at game city view Durban, they offered a refund but I couldn’t get refunded since I had bought it at Game west street. I was also told by the stuff at city view that game at west street are notorious for selling products that give clients problems. At game west street, I was told it has a cracked screen, that I dropped it even though it does not have a cracked screen and also no groves to show it was dropped. I wasn’t offered a refund like game at city view. My question is why does the same company have different policies ?

I will not be buying any items/products from game any more. Good thing I’ve cancelled my Game card because of the bad services received. How hard is it to get a refund from the millions made by the company ?
