RBL Bank — credit card application not approved without valid rejection

Address:

Hyderabad, Telangana, 500088

I have received multiple calls from rbl bank representative that they want me to allot shoprite credit card without joining fees. At first i was reluctant to take the card but after multiple calls from them i have accepted because they told all checks are please submit the proofs, then we will provide you the credit card. I have submitted the proofs to there representative. My reference number is #cchu287aa3. I got an verification call i have validated my details. When i check my status of my card "dear customer, your credit card application has not been approved as it did not meet the policy requirements of rbl bank" status they have mentioned, also they did not mention the reason for the rejection. This will reduce my credit score and effect cibil score when i try to apply any loan.
Please solve the issue or let me know exact reason why it got cancelled.
