ISSEY MIYAKE BOTTLE LEAKING

I have visited your Foschini store in East Rand mall where i experienced the greatest shock in customer services where no one is willing to assist me. <br> <br> I bought a bottle of perfume from your store in east rand mall about plus minus two months ago, and experienced that the bottle is leaking excessively. Due to that i am sitting with a bottle of perfume which is leaking so badly that I'm losing out extremely. <br> <br> I'm not even using it once a week maybe once every two weeks as i have many other perfumes to use too. <br> <br> Can someone please explain to me the procedure to return this bottle in exchange for a new one as I do not have the purchase slip anymore. I'm not a person who keeps slips as such in good faith that the product i buy from the supplier is of quality, specially products that's so pricey as this. <br> <br>
