Haha!! Maybe then you won’t prefer Amex as well 😬
They are just a call centre in India
Anyways jokes apart; OneCard is just a LTF free card I feel best used for small petty payments. One best thing I like about it as you don’t need OTP to transact.
When you make online purchase; there appears a notification In the app where we just have to open and slide to authorise. I find it easy to use for small tickets online payments likes Uber’s/Zomato etc
