damaged good being sold to customers

According to my understanding -staff need to check clothing before it can be presented to the customers, before it can even hit the floor, but that didn't happen with the boots I bought just on Sunday. O Sunday the 13th I bought a brown ankle boots at Jabulani. Tuesday the 15th morning left zip wasn't flexible but managed to put nit it. I only noticed the zip has is damaged and it was damaged from either the shop or factory fault. if its was some clothing then i could take it to the tailor but its a damn new boot that was bought a day ago. only if i had noticed before wearing that its damaged then i would have taken it back. I need Mr price to have a solution with regards to this as it something that can not be used and it wasn't out of charity i paid for it. if you guys can repair it for me i wont mind or exchange with a new one i don't care but I've warn the boots to work and i had no option to take it out. i FEEL VERY UNHAPPY , IM SO NO HAPPY FEELS LIE I WAS ******.PLEASE DO SOMETHING IS NOT FAIR FOR ME A CUSTOMER.I HAVE BEE A LOYAL CUSTOMER AND DONT MISS MY PREMUIM.SO CAN I PLEASE BE SATIESFIED WITH WHAT I PAID FOR.MR PRICE NEED TO RESOLVE THIS.
