Talk with your RM about the insurance policy
BTW maintaining 1.5-2L is not enough for preferred account ... It's maintenance balance is 2L ... I used to maintain around 4L ... Doing this will lead to delayed offers ... If not none
You should maintain more than the required balance for faster offers ... This might be the reason for which you didn't get. HDFC classic has 1L maintenance, if you plan to maintain 1.5-2L, you should have gone for HDFC classic account. You might consider downgrading your account to classic if you plan to maintain 1.5-2L. This is why I asked how much balance you maintain in your account.
