Used Goods

I bought a Uni*** Adjustable Velcro Waist Trainer online , Firstly the waist trainer is nothing like what they advertised secondly its been used , how on earth can you sell something that being used to someone else, <br> <br> All I want is my money back they must come fetch the belt that they delivered to my house & credit me back my money. I'm so disappointed i always buy from Groupon this is the first time this is happening to me.
