It's just a shame there was all the allegations of them not honouring refunds. They would have to work very hard for me to even buy one of their products and I was originally quite keen. Pinephone delivered what I ordered. I would have much more trust for them.
I asked for a refund when they kept delaying shipment of my Librem 5. I was simply denied and that was it. They told me I could still choose to receive the phone, but I don't want it since it's a bad, practically useless product now.
It's a credit card/payment processor thing, i.e. ultimately it's visa/mastercard, but it's up to the bank to offer to individuals. It's often available in other anglophone countries if your talk to your bank but I'm sure in some places they wouldn't do that. But yeah, years ago is too long anyway.
