I Found Hair in My Food Order From Yemek Sepeti but Only Got Partial Refund

In my order placed through the Yemeksepeti app, a large strand of hair came out of the pide. Of course, I immediately requested a refund. However, Yemeksepeti says they will only refund the pide. Apparently, I'm expected to eat the lahmacun. How can I eat the other item when both are made from the same dough and one of them had hair in it? Does that make any sense? I tried to explain the situation, but live support agents named Ö**** and A**** ended the chat before I could even explain myself. This company is unbelievably unprofessional. I will report Yemeksepeti’s irresponsible behavior to the Consumer Arbitration Board and across all social media platforms.
