HORRIBLE QUALITY OF PANTS

I bought shapewear from Shapewear shop. Never wore some of them and now that I am wearing them the buttons falls off after the second was. The one pants come with a broken zip. The pants bought either gets holes in them after two wears, buttons falls off or the zip is broken. It is costing me a fortune to fix my shape wear that I paid for and it is not cheap to buy shape wear. The quality of the pants is horrible, never expected something like this to happen.
