Dear sir,

I had applied for a Sbi Gold credit card. A lady executive called me up and promised me that definitely you will get the credit card to ur residence.

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

"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 rejectting my application. And how to applyagain.
