Only Premium & Super Premium Cards Discussion

I never used Bharatnxt - want to use specifically for my own business payments - which card/banks dont mind ? rewards doesnt matter - credit period matters. Also if someone can suggest any business card, i would Like to apply for same - already tried with HDFC - they dont give if you have retail card and in SBI - no one knows about business cards - Does Bhartnxt supports Amex ?? I heard that Amex dont mind even if you use it for business
