Worst Customer service experience ever

Oh my word , we do I start. I've never came across a store manager being so unprofessional. I have contacted Devland Hyper Epping spoke to the store manager regarding my chocolate mouse I bought the week of Christmas and used before the used by date which was the 2Jan 2022, and was told by the store manager Mr Allie to contact the Supplier as he will not be able to assist me, really. Because according to him I had to open it the day after purchasing the item in order for him to assist me, that you call bad customer service. Plus he hung up after I tried to explain why does items has expiry dates If I had to use it the same day or the day after... I'm so shocked for the way this store manager handled my situation. It's making me realize not to go back to shop at Devland Hyper Epping.
