I bought softstreme pants and the seam started unravelling within a few weeks. I went to my nearest lululemon and they decided to do a quality promise on it. The problem is that the same exact thing started happening again :( I’ve been following all the advice given to me about washing it inside out, on low, cold and hanging to dry but it still happened. I don’t think I can quality promise again? Is there anything that can be done or do I cut my losses
