Once bank employee confirmed me that my account is upgraded, I asked how can I get Platinum debit card. He asked me to open hdfc mobile app and asked me to first block existing debit card and then apply for Platinum card. I asked him, I don't have proof that my account is SavingsMax. All I see in my netbanking is just Savings account so what if I will be charged for annual fee for this Platinum debit card. He said I will not be charged as I placed request after account upgraded.
Till now I am not charged for debit card fee yet or any issuance fee. Its now around 3 months since I got Platinum debit card.
