Quality Assuarance of products needs to be rechecked

For years if not decades they have stood the ground in quality products but I don't know what's going on with their quality department. They are now having lot of **** things that are not durable. Just last winter I bought nice sleep ons that I only wear few times but the saw it's already falling of. The undergarments as well are falling off on stitching that was not happening few years back with woolies products.
