Retail Clicks Store Idutyq

My mom bought 2 packets of huggies extra care at clicks Idutywa after she open a oack of them she recognized that the nappy are not in good state because the baby just pee and licked as a result the baby had a nappy rush ,then she diceded to open the other pack to check if are they still the same only to find out are the same ,when she returns them at clicks they say the see them but they can't refund her just like that she lost +/- 500 just like that and we buy the new ones at shoprite Were were so disappointed how Wil you know the nappy if are not right without opening them?
