Domino's Pizza — Pizza delivered late and not even concerned about late delivery

I have ordered(#148) pizza on 8th Sep 2022 at 8.02pm and delivered at 9pm. App shown as 30mints delivery guarantee for every order. They are not delivering even single pizza on time as suggested in the app. My home is located within 1km from the dominos outlet(New No. 51, Old No. 166 Junction of Gandhi Rd. & Mudichur Rd, Gandhi Rd, Tambaram West, Chennai 600045). Still they are unable to make it.
Then what is the point & meaning of 30mins delivery guarantee which mentioned in the app. They not even asking sorry for the late delivery. Simply deliver person telling that as instructed by store manager, cancel the order if you don't want to receive. what behaviour is this?
They think like even if we don't buy, it will not affect their business. they have other customers to sell it.
