Sewing on Comforters are bad quality

I bought 3 comforters to the value of R1399 each. I have heard that their quality is very good and therefore I spend a bit more as it was good quality. I have received my comforters but are very disappointed. The material are good quality but the sewing on the edges was terrible. I even gave the bedding a wash and some of the sewing have torn loose. The quality checks on their bedding are not done properly. One would think when you buy from Volpes the quality would exception even the finish touches.
