RBL Bank — Fraud by agent

Sir/madam,
I was cheated by the executive of RBL Bank.
I got the Call from the mobile no. [protected] and he says that he is the executive of RBL Bank and try to convince me to take the RBL duet Card.
He messaged me with his whatsapp number [protected].
He says my Credit limit is 2.5 lac I got the msg from paisabazar that my credit card limit is 34000. I told him that but he says your limit is approved from RBL bank is 2.5 lac and this will show from RBL bank side
He told lie to me about the credit card offer:-
4.5% cashback on bpcl petrol pump
1 on 1 movie ticket free
2.5 lac credit limit
Which is totally fake.
According to his behavior it seems that it's a general practice of him.
please call and verify to another customer who was assisted by him
Please take the necessary action against him.
