Samsung a no show

I bought a Samsung Fridge just over a year ago and now there is a crack and another starting in the back of the fridge. I phoned the store that I bought it from, and they got Samsung to contact me. The fridge is still under warranty, and I didn’t think it would be a problem. Samsung phone me and what they basically said was that it was my fault and that they can order a part and come and do the job, but it will be for my account. I am no expert but where the plastic backing cracked the actual plastic looks very thin to me. When I told Samsung I am not happy they said they will send an assessor to come and look at the fridge. Samsung said the assessor will call me a gentleman , (Saheal Peerbux) did call me to say he will see me Monday. Monday he called and said he looked on the map and I will make him two hours late for his other appointments. ( I guess he didn’t do his homework, and my problem is not important enough) he did call me back to say Samsung said he must come and take pictures and scheduled another appointment for Tuesday he said it will be early (10:00). It is now almost 2:00pm and no show or call. I phoned Samsung and Mr Peerbux and there is no joy.
