Sneaker review: Running shoes

Hi, kindly I need to return my sneakers I bought it a 2month ago and I found out there is something wrong in the front of the sneakers as shown in the attached picture

I went to the store where I bought the sneakers from and they told me that I had been month ago so I can’t return it or change it with any other product and the only way to complain is to write on the website

My question is how can I bought a original sneaker from adidas and to have a manufacturing defect within a 2month and the store refused to change it for me either to repair it

Thanks.
