It’s like they don’t even know they have already refunded me, and they aren’t asking the money, from what they wrote.
For further security, I have temporarily blocked the card from the app.

It sounds like the claim Is over and done with.

As such, I highly doubt they'll take It further.

I don’t know if I should leave the card on amazon or remove it. Maybe if I remove it I would look suspicious?

It's a prepaid card so If there's no funds on It, they cannot debit It.
