Google India / Tez — Google play tricked me and deducted payment

I was opening linkedin in my app on my mobile. I saw a message from linkedin of an offer that i can use their service for free for a one month period and if i dont like it, i can cancel for free before a month. It further said i can explore more plans. So i took a step further and explored all the plans and then i decided that the one i was offered was fine. So i went back and clicked on and on payment page, it showed me the amount and googe play payment details with my card details already stored. Since my payment details were stored i went with the payment thinking its just faciliting my payment. But actually it turned out, it tricked me into buying a similar product which didn't have any trial period and amount was debited right away from my account

This is not expected of google and it seems fraud. I want my money back and not charged by tricking me into
