Complaint Review: Waist gang society

I saw this company on instagram bring endorsed by kim Kardashian and khloe Kardashian for waist trainers from premadonna 87. So I thought kre me try it out. I ordered and the thing was too big. I emailed and messaged several times on Instagram and their personal email for days no reply. When I try to exchange for the correct size the thing was too big they rudely said oh we don't exchange. If something you buy online doesn't fit and they won't exchange for almost $150 that's a rip off instead of trying to resolve the issue they encouraged me to file a claim which I did immediately . Bad business Premadonna!
