NIKE - POOR QUALITY SOCCER BOOTS

I bought a pair of NIKE JUNIOR MERCURIAL SUPERFLY 10 ACADEMY KYLIAN MBAPPE for my son in May and 3 weeks later they were starting to come apart at the front seam. I took them back and the response was that my son plays soccer on gravel. I explained to them that my son DOES NOT play on gravel but at school and club soccer. They refused to assist even through these shoes are poor quality and are starting to split. I have 3 sons and buy 3-4 pairs of soccer boots from them every year and have never had this problem before (and my sons' play on the same fields as they have always played). i will be buying another brand of soccer boots going forward. Very disappointing service from NIKE :(
