Reversible Door Lie

First of all it took 19 days to deliver the Defy reversible door fridge I bought, once I got it on Friday the 15th of December 2017, I tried to reverse the doors all went well until the last *****s at the bottom of the fridge does not move at all, I stripped my tools and my brother stripped my other tools to get it loose, I tried to call Defy, no answer, I understand it is holiday season. So I called the Cape Town branch in the beginning on January for help, they gave me a number that doesn't work, I call them back they argue that is the number, I tried again, I called them back and they said they will give it to the right person to call me back. Two weeks later today I call them, they put me through to a services guy who says it will cost me R450 to reverse the door. I call them back to ask why must I pay for something that should work right in the first place? They put me through to management, no answer, numerous times then the phone dies and I call again and hold again no answer over and over, then they say they will give my number to management to call me back, HOW LONG IS THAT GOING TO TAKE? If they can't fix this then I want my money back so that I can buy a real fridge which doors can reverse like it should.
