Jet Airways — I can't understand the safety instruction

Address:

Chennai, Tamil Nadu, 600128

Recently I travelled to Coimbatore from Chennai international airport. As soon as I enter in to the flight they started giving safety instruction in two languages which is English & Hindi. I can’t understand both the languages because I’m from Tamilnadu & my mother tongue is Tamil. I hope the airlines doesn’t have any mandatory rules saying that only educated people can fly. When any accident or an emergency happed, I do not know what to do. hence the safety of the journey is ...?

I can’t understand the policy of the jet airways they are operating the flight for local Tamil peoples hence the instruction as to be given in their own language rather than giving importance to other language.
Hindi is not the national language for India it’s one of the official language that it.
Hope you understand the issue. Pls take necessary action to rectify the issue.
