Reliance Digital — Sales Man Billed Extended warranty by cheating while buying fridge

Respected Sir,

I went to bought LG refrigerator in reliance digital store sonipat on 21 Mar 2022. Salesman told me that fridge comes with extended warranty and can not be sold without extended warranty. They swaped my card even before the billing and later gave the bill quietly in a paper bag.

I came home and found out Rs 1999 have been charged separately and when check online this extended warranty is voluntary.

Sales Man Name -- Ravinder
Store -- Reliance Digital Sonipat

I want to cancel this extended warranty right away and want my money back.
