RBL Bank — rbl credit card application pending

I had applied for rbl credit card on aug 8th (Application number: [protected]). 2 days after i had received a call from one of the rbl executive regarding document verification. They asked me for local address proof. I just send them through email that they provided to me ([protected]@rblbank.com). 50 days got over i didn't get any call from their end. There is no notification to me till date at least they can tell me the status if they can't provide means please notify me with the reason. So i can find some other source.
