Another issue which i want to highlight is,
In general, refunds are processed to the same card from which you made original payment, even if you are now using replacement card.
For example,
Card A - Old card from which you made payment of Order 123.
Meanwhile, Card A gets lost, expired etc and you get a replacement Card B.
Now you want refund of order 123. In that case, refund will still be processed on Card A, even if it's blocked, lost or expired and the refund will reach your bank and get stuck.
To get back your refunds stuck in old card, the same above "credit not received" dispute case applies.
