In my case requesting priority team worked for me I kept on mailing until they approved my card Luckily I am holding both Regalia and Biz black as they approved Biz Black as Floater cardHDFC Bank is quite weird sometimes. It gives an application number which doesn't reflect in their system. Gives an email of application declined and then gives SMS that card is approved. Got my BizBlack today. Will recommend going via offline channel to get this card. Online/Grievance/PNO didn't give the result but one phone call to RM at branch got things rolling.
