**** sneakers, only wore twice and they are torn

I purchase sneakers last year November and I only wore them 2 or 3 times and the sneakers are already torn. I tried to return the sneakers and I was told it's pass the 6 month warranty period and they cannot assist me. I bought the sneakers cash but on the same day I purchased some other items using a card (3 Ladies T-shirts and 2 Men's T-shirt) and I have a bank statement for that transaction. I don't have the purchase slip for the sneakers but I was there at the shop they can look into their cameras. I am very disappointed with the way they handled my quiry without doing any investigations - I bought those sneakers because I trusted the brand I'm so disappointed with Guess Access Park.
