Query: Still waiting for a piece!

Would be a great system if Aliga Online could actually send me the right part. The original set was missing an extension so I emailed (in November) and finally got a part 3 weeks later, which was the wrong color! Emailed again, again and once again....now it's the end of February and I still don't have the correct part to finish my closet. Not worth the hassle.
