Constantly use the card and try to utilize up to 30% of the credit limit of MoneyBack credit card. Regular usage of the card will initially provide you the opportunity to raise the limit and eventually upgrade it. You can also reach out to them but from my experience the relationship manager asked me to have frequent checks on the website. But I think if you are eligible for the same then they'll notify you.Hi. It has been almost an year I have been using hdfc Moneyback+ ltf credit card. I now have an upgrade offer to Millenia but it's not ltf. Should I upgrade or wait for Millenia ltf offer?
