I bought several things from allnetchina.cn including:
1 Rock Pi 4 A+
2 eMMC 5.1 16 GB and 2 uSD to eMMC adapters -> the adapters don’t work at all after many attempts.
1 Rock5 B Acrylic Protector with the Fan -> The fan doesn’t work.
So? I wrote an email to firstname.lastname@example.org on the first of December to have support but they never answer me.
Do you know how I can contact them?
