There is an option to upgrade from Vetta to Zenith. Below criteria should be met by card holder;
1. Existing card should be more than 6 months
2. Current card should have limit more than 5 lakhs.
If both criteria met, drop an email to Credit card customer care or call to customer care. Your card will be upgraded to Zenith.
@nadeem199417 - BTW what is the limit on your Vetta credit card?
