Terrible customer service/post sales support

I purchased a dishwasher online from Hifi Corporation on the 10th of July. They delivered the order a few days later. When I received the order I noticed that the dishwasher was cracked on top. So logged a complaint to them. Ever since then I have received no feedback from them and the only update I can get is when I phone in or chat to them on using their website messaging service. They make no attempt to inform me about the status of the complaint. I don't see why I should have to always phone in to find out about a problem that they have caused.

The dishwasher is still in the middle of my kitchen and the last I was told is that they will update me on Monday. I have no faith that this will happen as on all previous occasions they have not bothered to let me know what is happening.

I have requested that I want my money back as I do not wish to do any business with Hifi Corporation ever again. If this doesn't happen I will take legal action.
