Received incorrect parts and now silence...

I am so disappointed. I ordered a part for my Z1 Compact , I waited over 3 weeks for the part and was very patient considering the turnaround time on the website is 2 weeks. When I finally got my order which was only last week Monday after waiting since Friday 16 January 2015 it was the wrong part and wasn't even for the Z1 compact. I then tried to contact the supplier and have heard absolutely nothing. I don't know about everyone else but I definitely don't have R 400.00 to just throw down the drain. I am seriously disappointed and quite disgusted with the level of service I am now receiving after being so patient about this whole thing. I cant say that I would be happy ordering parts from this company again and not because of the time period it took but because of the utter lack of feedback and terrible terrible customer service.
