Poor customer service...

I went all to excited into Dion wired Canal walk to buy myself a new microwave... All the way from Mitchells Plain to Canal Walk... At the till when I purchased it, I asked the cashier if he can open it for me to see if its condition is perfect, I have all right to ask, I work hard for my money... He continues to reply saying its not necessary the manufacturer seals it and there is nothing wrong... I return home to take it out of the box and plug it in, to find the door is not aligned and the front keypad and door has scratches. At this point I am fuming as I need a microwave, I call the shop and I speak to more than one person before getting to the manager. He tells me you must bring it in, I ask him how are you going to compensate me for traveling up and down after I asked to see the microwave before walking out... I demanded that someone come replace the microwave, because it is a effort and costly for me to drive up and down and it was their mistake, and they refused! Very disappointed in a store with such a status. Dont just please your customers with a smile, going the extra mile is out the door.
