Yes I also received the duplicate application notification as a reason for the decline. Please see attached. I applied offline through Tab. When I reached out to my RM mentioning that I have no clue about the duplicate application bank was referring to, I was told it was rejected as I was already holding three cards from them at the time of this 4th application. Though the wordings of the decline message are misleading and confusing and is not even near to the actual reason my RM stated, I had no other option other than believing him. I have now closed one of the cards and would reapply this month as 3 months are about to be completed very soon post rejection.
