Pampers Jumbo packs

My daughter received 2 x Pampers Jumbo packs as a gift which is not suitable for her baby. On phoning Game who stocks the pampers and after checking that the barcodes correspond with what they have in stock, they told me they cant exchange it because of the sensitivity of the item. Yet in another breath she says if we know exactly when and where it was purchased we can exchange it at that branch. What a load of bull. I am extremely unhappy with their service and attitude.<br>
