Damaged R600 Puma sneakers after two weeks.

I bought my five year old daughter R600 puma sneakers for school less than two months back, after two weeks of wearing the sneakers stricktly to school the soles came off. i then had to proceed to purchase her another pair of good quality sneakers from another shop since she had to continue going to school. Last week was the only chance i got to go and report the matter at Edgars Polokwane in Landros Mare and I spoke to a lady called Fele, she told me that even though I do not have the slip and do not remember the exact date I should bring the shoes and she would be able to detact the piurchase date by making use of the last four dsigits on my bank card. This morning I went to the store with the shoes and she reffered me to a certain need I mention very rude Mr Joosuf Pemma, the warehouse manager who took one look at the shoes and told me that the shoes were clearly damaged from excessive use. Need I mension that he further said that there is nothing he can do for me when i asked him if it was possible for a R600 rand sneaker to be used excessively in two weeks by a five year old while her sister wears the same brand of sneaker from another store that is two years old and strong.
