First of all, really sorry to hear about the chargeback.
2nd, are you absolutely sure that 900+500 = $1400 was actually taken from your bank account? As far as I know, banks can't and should not refund more than the total order amount made.
I would recommend you speak to someone higher up with Shopify payments or Stripe again and to see if they would escalate your case and do an investigation. Explain that the $500 was already originally refunded back to the customer. You should not have to refund more than the original amount plus fees. The bad-actor is essentially making $500.
It’s likely that the customer has a long history of doing similar things. In the future, try and use a service like IPQS to detect high-risk transactions and avoid them as such.
