Domino's Pizza — Dominos denies that I've placed order

Address:

Bangalore, Karnataka

I have called dominos pizza at park square mall, Bangalore at 3.30 pm on 22nd mar. A lady took my order and confirmed. I called again after 40 mins that I did not receive order but I was told its on the way. I called again at 4.30 pm and the staff (the lady and some guy Prakash I think) said I never placed an order. They said they won't give pizza free but they'll give garlic bread free if I place the order. Please take action against those incompetent and unethical people
