Beyoung — 4 t-shirts

I've ordered 4 XL size plain t-shirts which was way too big then the normal XL size so I've exchanged it with L size which I was expecting smaller but it was the same as XL, there was not such difference and the main concern is poor quality of the T-shirts. It is not at all up to the mark and not even just similar to the picture as shown in the website. I want to return the product and wants refund for the same. Kindly provide me the solution on call and do not close the ticket with resolve it, customer care executive and their service is so pathetic that they are blocking my calls and not even answering about it. It's company's fault that they have delivered bad quality products. I do not want to exchange or return i want refund only. So many times i have raised the ticket and mails as well but there is no response at all
