Imperia and DCB/Infinia are unrelated.RMs won't get you any Infinia/DCB by lowering criteria even if Imperia. Criteria fulfilling (salary/CL/spends) is the only way. Don't go for Imperia with that hope
DCB to Infinia upgrade was supposed to be on HDFC salary account + salary criteria fulfilled + credit limit. Already gad DCB for 2 years.
But RM and BM made false promises and backed out.
So, no hopes from HDFC.
