When i tried to eat the food i found some hair in the food and how can i eat such food and i tried contacting the customer support over chat and they are just annoying with late reply and they are not even responding to the messages i waited around for 20min but they are not even responding and the agent name is vanya and i asked her to respond she didn't and then i told that i'm recording the whole conversation she just ended the chat session and exited the chat.
