State Bank Of India [SBI] — Credit card status

Address:

Thiruvananthapuram, Kerala, 695581

Dear sir/Madam,

I had applied for a SBI Simple save credit card. I got verification call from a lady and it was all done. Even the guy from bank told me that it was processed and approved by the system and is moved to HQ.

I got one message from SBI stating your application is under process. Then next day under online status of SBI credit card, it said,

"We regret to inform you that your SBI Card Application could not be processed since it does not meet our policy. We thank you for your time."

I have given all the documents .Please tell me what are the reasons for rejecting my application. And how to apply again.
