SUN SPORTS - Karachi, Pakistan

I did a purchase one month back from Sunsports Khada Market Branch Karachi. Same day I intimated the shop manager about the Addidas Shoes they are defected. It was told to me, " sir, no problem you will get the claim in 3 to 4 days". Now when I submitted the product it was told to me products sold under sale can't be exchanged. Which sounded really funny as the purchase slip clearly States in Point no.4 as product damaged/defected can only be claimed if returned with in 6 months. I have attached the photo for perusal.
What kind of a joke is this where company mentioning a point about claiming a defected and damaged product, where as on the other hand staff working in store and head office are unable to read and understand it completely.
My product was defected and damaged from the very first day. You people although are dealing with world class product "Adidas" but there is no customer services and products are defected in your outlets.
Kindly resolve my issue urgently as it's been already too long. Otherwise provide me the contact numbers and e-maill addresses of your international offices. You people are breaching your company policies yourselves and Sunsports is selling defected Adidas Shoes.
