Up until hours ago my pending PayPal claim seemed lost in a different form of silent purgatory, but the refund appears to have finally been authorized as of tonight.
I ordered the phone on 5/12, cancelled the order and filed a PayPal "item not received" case on 6/26, escalated the case to a formal PayPal claim on 7/16 (under pressure from PayPal's "close or escalate" automated ultimatum), and as of now it appears the claim finally got refunded on 8/12.
Not a single email response has ever been received from numerous attempts to contact sales@pine64.org throughout this total waste of time and frustration. They ignored requests for updates before I cancelled, seemingly ignored the cancellation, filed an "item shipped" update in the PayPal case on 7/8 despite my cancelling the order on 6/26.
Hopefully you've asked your bank/creditcard to reverse the charge?
