Bhai Kisi ko NRV ka idea hai how much is needed to procure LTF infinia // DCB ?No harm in trying to check with RM but they would push for cross selling other HDFC banking products. My DCB plastic got upgraded to Infinia and spends 7.5L of spends and 8L+ limit on DCB seemed to be a strict criteria if your TRV with HDFC is limited and if you don’t fulfil the salary criteria for Infinia.
For manual CL increase would suggest if you have good in hand salary then do push through RM / branch.
