Domino's Pizza — Overcharged for order and receipt not given

Address:

New Delhi, Delhi, 110016

I ordered 2 pizzas and they charged me extra 70 for each pizza saying it is extra cheese. I paid the amount and bill was not given stating it will be given with pizza. I calculated and thought I was overcharged, I demanded bill again but not given. When they gave pizza I said if I am overcharged I am not gonna give any money for Pizza still nothing. Argued with manager later and he threatened to beat up and also call the police. Humilated and scared about what would happen had to leave the store. I am student of Final year at IIT Delhi and was afraid of fighting. I want issue to be resolved.
