Jiomart — Took money but did not deliver items

Address:

Bangalore

JioMart is looting its customer by taking money and not delivering items.
I ordered my groceries on 03-Oct-2020, it was delivered on next day with some items missing. I told delivery guy about this and he said he will bring tomorrow. That tomorrow never comes. I've raised multiple complaint in Jiomart customer care but they have not taken any action yet.
I'm fed up of raising complain, now i'm planning to take this matter to consumer court.
