Cross at Cross Trainer

The service was great that I received, the people are very welcoming, but when I purchased a pair of Superstars for my son, my concerns were not treated seriously. The pair of sneakers had a default within a month of just buying it, actually the month had not even ended. I contacted the store, they said I should take a photo and WhatsApp it, I did but the was told there is nothing wrong with the sneaker, after a while my son still wear the sneaker and I see that its not normal for it to be looking like its torn, and I went back to the store and they took pictures saying they will forward the matter to the factory, where they will determine if its a factory fault or not. it hasn't even been 3 months and that sneaker looks like its 5 years old, from the torn look, I feel upset because I bought another sneaker, same kind for my niece, but no one cares to sort out my concerns. all I asked is for them to look at the problem and find a way to fix it, I don't want refunds or anything just make the tekkie look right, even if it means exchanging the faulty-looking one. Otherwise I will boycott the store. I will not be happy until I get proper service regarding this issue.
