Poor service

I bought Pampers nappies at Dischem a week back however I have noticed the nappies seem to be defect. I have thrown the receipt away already and I reached out to Dischem to find out if I can return the pack to the store and they told me to contact Pampers. How is that possible? Did I buy the stuff from Pampers directly or from Dischem? To date there is no response to that.
