Bad service at OK furniture Vryburg

I bought a fridge(R4 490.00) at OK Vryburg on black Friday 23 November cash. Till today I didn't get my fridge. I bought it at 06:51 in the morning, I believe im the first one to buy it. To my surprise when I get to the warehouse I was told they've been all collected have to wait for the following week and by that time I did hire a transport which he charged me half price as I asked him to come and collect for me. I've been doing follow-up on the delivery till now no positive feedback. Why are we treated like this by this big furniture store. Is it because we bought it cash so you are not making much commission so you treat us like this. I've been waiting for too long and I believe they need to take responsibility of delivering to me. Account sub: ***. It shows its OK policy to take this long to deliver, my big brother also bought at OK Delareyville for R3500 bed still not delivered and my younger brother also bought at OK taung for R 8000.00 (Fridge and bed) still not delivered and he was told he have to wait for those who bought for him first to collect. But on my case at Vryburg I bought first but those who bought after me they have collected their fridge. This is bad bad customer service I regret buying from OK
