Bad attitude from Staff

Good day

Last week on the 16th of May 2018 I bought a couple of items from Dis-cem and amongst the items I purchased were packs of popcorns. I had noticed later after eating them (which one i had eaten half way) that the expiry date was 09/04/2018. On the 22nd of May 2018, I got time to go to Dis-cem to let them know that they have expired stock on their shelves and that i wanted a refund. A lady by Salome at the customer care told me that, her axact words (with attitude) "so, whats wrong with that". I was so furious as I did not expect such a response. I am really dissappointed by this.
