Applying Flipkart axis cc through Axis app

Axis Bank cards were LTF just few days ago…why didnt you apply then? 

I applied. They said since i don’t have a surname, they cant process it further. 

The strange thing is that I am already an Axis neo cc customer for the last 4 years and during the application process of Neo, verification was done manually.  But now when i try to apply through the website, they are saying V-KYC cant be done because of not having a surname. So now the only option left for me is to upgrade through App. But in app, its showing charges currently for Flipkart cc 

I upgraded my cc through the app, but they are charging me joining and renewal fees. Should i cancel it (Flipkart Axis cc) later this year or keep it since its benefits outweigh its con.
