HDFC Bank — HDFC Credit Card Application

I had applied for a credit card on the HDFC website and the card was approved in principle due to my long standing credit history and other factors. However the card has been stuck in process during all this time and there's been no update since then. I had tried to mail the customer care and they haven't replied as well and this is well over the 2 day SLA that they have mentioned in the mail. The customer care number that's provided is also despicable and it's just the IVR service and no human customer care agent to assist with the issue. Totally disappointed with their service and hoped more from one of the prestigious banks in India
