Branch manager and staff needs help on product knowledge

Yesterday I wanted to have a complete chilled day and relax with snacks. My wife ordered a few things via the sixty 60 App because it's convenient and hassle free. Upon the delivery we started opening up the lancewood dip . We immediately see the texture is runny. The texture is a thick smooth paste . Before we did anything My wife called the checkers branch in langverwacht and spoke to the Branch manager (langerverwacht). He advised to bring the item as he will liaise with the supplier. I arrived at the store and the lady who assisted advised she can't assist as the item was bought on the App. The fault must be logged on the app. My wife then so but minutes later she told us she can't exchange because a refund was processed on the app. I was so furious that I return all my items back. Before we did anything irrelevant we contacted them for advise . Yet we listened to what they told us but it's not what we wanted. We wanted another dip. But because of there pathetic advise we returned all our goods. Bare in mind the branch manager advised that I bring the dip to the store - Why couldn't the delivery service collect the item as I paid delivery fee and do the refund on the App. But instead we listen to what experienced retailers are telling us. Where is my delivery fee, seeing that you wanted me to drop the dip. Inflation cost is so high yet the store manager have time to play mickey mouse with me. Yet He will go down on the lancewood supplier or merchandiser for putting stock on the shelves that will expire 21/11/2022 almost in a few days but yet you giving your customers the wrong idea. One small thing miscommunication would've been resolved by a thank you but don't tell me something and still leave me angry walking out of the doors
