Bajaj Finserv — Registration without consent

I, sumesh sharma, am having the bajaj finserv card for last 1year. I started to receive calls regarding bajaj health card 2-3 months back and then messages that i have accepted health card for which i clearly denied that i am not interested in buying this as i already have one. On 22nd june 2020 i received a message that rs 707 are going to deduct from my account in 10days. I "opt out" from that still on 24th july 2020 rs 707 deducted from my account. I never gave consent or willing to buy this card. Bajaj finserv having account details doesn't make them authorise to deduct any amount from account without consent.
