Branch manager no service

went to clicks Ferndale to exchange my child's nappies as my husband bought the incorrect ones I was rudely "assisted" by a lady who said she is the branch manager Precias who didn't even bother to assist me. The pack was bought as is with the plastic smudged at the bottom, unopened, unused she did not assist me instead said with a mouth full of other words "you can send an email if you want to"
