There were consecutive cases here - once the delivery boy never turned up. And after a lot of bickering and argument, managed to get a coupon for a meagre amount which eas no consolation.

Extremely bad and rude customer care. And extremely naive executives, doing anything since they have started thinking they have a monopoly, which is a misconception.
