Refusal to take back non satisfying products

<p>I bought 5 jumbo packs of pampers active from pick'n pay mall of the north, just started using the first pack and it gives my baby bum rush. It also look like it's leaking cause my baby's bum is always wet when I change her.</p> <p>I called the store and asked the store manager to swop the products with premium care for me but he refused saying that if I have problems I should call pampers since its their product. If they can't help customers with the products they are selling, why are they selling those products.</p> <p>Now I'm stuck with 4 unopened packs of pampers I cannot use, all I needed is to exchange them with premium care and pay the difference in price.</p> <p>This is proof that customers should only buy pick'n pay branded products since its seems like thats the only products they can assist customers with if not satisfied</p>
