Addidas - Complaint for manufacturing defect

Sir / Ma'am

Through this letter of mine, I wish to inform you that I had purchased from your Ambience mall, Gurgaon store a pair of running shoes and yoga pants. I had cleary expressed my reason for buying the products. Since I am a athlete, trusting on your brand and patent name I had purchased *,*** shoes hoping it would last atleast for some years but to my horror both the product didn't lasted for even a year. I had made the order in the name of Vanshika. Your employee also made several claims stating this best product and money spent would be worth, but no it isn't. Addidas is such a huge name and a global brand, and this kind of service wasn't expected from you.
So, I would like back my refund so that i can continue my training or repair the shoes, but do whatever, at the earliest. I am attaching the photos below for your reference.
