Bhai, I maintain less than 1k in ubi. N they still issued rupay platinum to me. 🙂
Ok Bro. I have shared my experience which might vary bro. infact I saw the error my self (in the last few months), so was confident.
But I totally trust you. and it might be different with different accounts (My account was with Corporation Bank which is now Union, I took Rupay Platinum only after it became Union)
