[Resolved]  Kotak Life Insurance — no response on email

Recently I have been receiving calls from Noida[protected]/87) stating about the 'Kotak Smart Advantage' plan with following features:
(a) Pay premium of Rs 50,000 per year for three years.
(b) After three years Kotak Life Insurance returns Rs 2,32,000/= as a maturity value.
(c) It means on contribution of Rs 1,50,000 your net gain is Rs 82,000 i.e. more than 50%.
(d) Calculation chart claimed to be from Kotak Life insurance was also provided to me.

I sent an email to [protected]@kotak.com with the attachment to confirm if such plan with these features exist. Even after two days no email from Kotak has been received. Why no reply from Kotak and what are its intentions?
