Credit Card Drama

I applied for a standard charted credit card via a phone call agent. (sir you are eligible for a card call wale). I wanted a platinum LTF card but she said after submitting the details I am eligible for another card with fixed yearly charges of 350. She told me she would pay me 350 after I received the card. She called back-to-back during office hours. So I blocked her. In the last two days, she has called me from 7 different numbers, at least 20-25 times. Finally, I picked up her call, and she told me that she would have to pay 3000 rupees fine If I won't process my card. She will G-pay me 350.

Should I do the v-KYC?
