The told me my iPhone could not be unblocked because it was presumably blacklisted/lost. I manage to get the previous owners papers and after emailing them 10 straight days they still did not reply. I then logged it with trust pilot and eventually someone replied that I would get a cash refund in 3-5 day. That was the 3 May, 8 days ago. Still no refund or response to my emails. I would give them zero if there was that option
