I dont. I paid using debit card. I never thought that field is relevant. Sometimes I fill weird name in name field just for fun (not when making tax payment).Yeah there are glitches today I found couple of times in the evening. Came back now. Just did a test payment of 100 on hdfc pg via sbi cashback. Btw do you use all capitals under name under credit card details while doing payment. On using just first alphabet capital for both name and surname I found payment getting failed on sbi cashback card.
