McDonald's OLD burgers atleast 5 days old, if not longer!

Got 2 cajun chicken burger meals at McDonald's Ottery drive through. The burgers looked old, atleast 5 days old! 😖 The milkshake that I had left in the fridge turned to water with a bit of white cream on the top! I've tried calling numerous times but the phone just ribgs. The lady that also took the order wasn't really friendly either. Can someone from McDonald's please contact me regarding this! I spent more than R120 for something that I couldn't even eat! 🤢Money just waited!!! 😖
