Domino's Pizza — non delivery arrogant talking

Address:	Chennai, Tamil Nadu
Website:	pizzaonline.dominos.co.in

I order a pizza on 7th october at 9.04 pm but not was not delivered i was waiting for more than 1 hour and called to the branch (Venkatakrishna road, mandaveli branch) they simple saying will get delivered in 30 mins or else i can cancel refund will be initiated in 7 days, what kind of services very very very bad
They are giving commitment for 30 mins delivery or free of cost, but they are maintaining the standards, its really bad compare to other pizza companies dominos rating will be in minus.
