Is the MS Office license sold on flipkart genuine?

[HappyPerson]

I wanted to buy MS Office 2019 One time purchase from the flipkart ( link attached below). But I am confused as the price mentioned seems too good to be true. I wanted to know, that can unsocial elements who are active in facebook selling fake educational or organizational office keys also doing the same in flipkart or Amazon. Are these sites safe for MS office purchase considering product is rated more than 4 star and seller rated around 3.9. The only red flag I could see is the mentioning of mobile number in description for better deal ( when I checked it in truecaller, it is linked to some individual in Patna, Bihar).
