2 pare of nike tekkies in few months rip

Good day <br> <br> I bought Nike tekkie at S&K store in Johannesburg and I had for 2months and air bubble broke. I wear a tekkie once in like two week. I when back to the store and they said it's Nike problem. I bought other Nike again and after few wash the tekkie start to rip. I when back to them again and the owner said Nike refuse to take it back.
