I ordered a couple of Android TV boxes which didn't do what I wanted them to and returned them within a couple of days. I went through the normal return procedure and got all the paperwork correct, I had the items returned to them at great cost given that they needed returning to Germany. Contacted them several times and although pleasant ineffective. Sent proof that someone at Geekbuying had signed for receiving the return but they claimed not to have received them.
After a bad one star review in Sitejabber they seem to have found the items and refunded the items in full. They asked to give them a good review but I can't as the process was still appalling and aggravating.
