Ajio — unprofessional

I bought a product from the website and simply requested for an exchange. The exchanged product never reached me and when i asked them where it is, they said that it's on the way to their warehouse. They keep delaying and mismanage things and never answer appropriately
I've been asking to exchange the product for about two months now. All they do is make fake promises and give stupid reasons for not being able to do it.
