I don't visit this site regularly any more since the theft and I've just seen this post - I've emailed you at that address I look forward to you sending my stolen bitcoin in full.
Though you have replied him after about 4 years, let's be hopeful that he will reply and maybe get you a refund. If they were serious about refunds then they should have made a huge announcement and a big campaign to notify the victims vs just replying in these thread where people take so long to revisit or even just completely forget.
