Haldiram Bhujiawala — Found iron screw in Haldiram food

I ordered Froed rice and manchurian from Haldirams Asansol through Zonato on 13 September 2021. They called and said it was not available so they will give paneer chilli and fried rice instead. To my disgust I got an iron screw in my first morsel! I could have swallowed it by mistake. Haldirams is a big brand. This is too low standard of quality.
Please look into the matter. I am unable to add photos as the size exceeds. I have mailed as well and attached photos.
