Bajaj Finserv — Company doing fraud with customer

Address:

Gwalior

My name is Ajay Kushwaha an old customer of Bajaj Finance Company I received a mail for Bajaj Finance Elite card subscription on 27/10/2021 which I have confirmed to Bajaj Finance on 28/10/2021 by mail here
It is true that it is fraud, I was told this mail is correct, on the same day I applied for card membership and I paid the fee which was Rs 3000 in it, which I have proof of which I am not able to have any contact with the company from that day itself
Nor is there any customer service please help me thank you
