I bought Grasshoppers shoes for R479,95 shoes are

Good day. On the 10/02/2015 I bought a pair of Grasshopper shoes for R479,95. On the 03/06/2015 I took it back because the shoes were torn. Mr Conrad Peters said they only exchange gods after 30days. I just wanted Edgar's to sent the shoes for assessment to say why they cannot exchange or refund the shoes which my son of age 9,wears. Mr Peters say according to his Customer Liaison Mr Buntu Mkize the shoes cannot be exchange. I just want them to sent the shoe for assessment at Grasshoppers because this is not the first time I have this problem. Egars does not manufacture the shoes so how to there workers know about wear and tear. I am not happy to pay so much money for such bad quality
