Getir Sent Me Rotten Chicken and Refused a Refund Unless I Kept The Smelly Item

We bought chicken breast from Getir, but it seemed like a rotten chicken was delivered—it smelled so bad that within an hour, the entire house was filled with the odor. When we contacted them, they said a refund would be issued. However, the next day, they called and said that we needed to keep the smelly item for them to take back, otherwise, no refund would be given. What kind of nonsense is this? Do they expect me to keep a foul-smelling item in my home as if I have nothing else to do? It’s really shameful.
