Street Style Store — I want you return my boots and buy something else

I have received "to all the single ladies boots" order #8322363 but the fit is not at all impressive and I did not even like the product. I tried to return it through the app but I don't know which is it showing as if the product is under exchange so I want to return the product, I have been trying from a week to call Street Style Store customer service, but no one is answering. I really request you to solve this complaint as well. I want my order to be returned. and the money must be refunded.
