Okay... this is almost too embarresing but i owe to reveal it to avoid confusion. i was so convinced that i typed the right info. then i checked my card.( some of the numbers are almost ineligible) and i noticed that just 1 number was not what i saw it was at first.
so false alarm. i even submitted a ticked. to the customer suport: please disregard it. i am very sorry. also ty to the people taking time to reply. i feel like such a fool.
sorry if i caused any confusion!
