Agree, specially when you do transaction after a gap of 2 or 3 month, they initially block the transaction citing random security of card misuse and we have to manually unblock the card.Hope it was like that.. today did txn at reliance digital website for 7k, txn declined, card blocked, app login blocked. Can be unlocked by calling customer care or email.
Card is few months old with regaular txn of few thousands, only personal, in multiple websites.
Every card/bank has their own drama.
