Bad Quality

Quality of your products - i purchased a pair of sandals for my son last year, the sandal snapped and i went to exchange it in october at the la lucia branch to my dismay the sandal snapped yet again in december. i went to the Gateway to exchange, but due to the product being so fragile i requested the broken sandal for a sandal of more value and was willing to pay the extra amount, however i was advised that it would be impossible to do that because the sandal was damaged, i thereafter requested for a bigger size and yet again i was told that its impossible because the sandal is damaged. Are the products made with such cheap material that it damages every two months, yes i understand wear and tear however the cost of the product is not of cheap quality. How does such a REPUTABLE brand not understand the customers needs and provide better quality and efficient customer service? How can one positively promote a store when we receive such bad service and poor quality products?
