Overhyped but did not deliver on promises

They make false claims about their shapewear and their social media is very misleading. When I showed them the pictures they blamed the supplier. I then exchanged the shapewear for one that they assured me was more suitable for my body shape and my needs only to find that its just as bad as the previous. I then had to pay for courier to get the item back to them for a refund which has yet to be paid,its been a week.
