Bad attitude

On sartuday around 9h00 we bought 5x mixed fruit of Jam tins my aunt made a mistake she was suppose to buy Fruit Salad not Jam. We noticed that when we got hom, i took back the Tins to the store when i got the ive asked for the exchange to the lady at till 12 and when i go to the shelfs i found that the are no mixed salad tins that i wanted then i told the lady at the till if she can refund me, she called the supervisor Ashley to Authorise Ashley was very strictly rude she even tell me that the Tins are damaged and next time they wont refund or exchange if i come with damaged tins, she even go to the shelfs and check she found that the are other tins that are damaged ,She didnt even bother by apologising because it was the store's fault not mine.
