I have been gone for a week, I still haven't heard anything from Lemon and haven't received my refund.
I guess its time to consider the money gone.
I've been occasionally browsing the internet via wifi on my tablet, I don't have the energy to do pretty much -anything-.
As a user of computers and internet myself, my assessment is that sending bitcoins to someone (who you owe a considerable amount to) does not require more energy than browsing the internet and posting messages on Bitcointalk or Twitter.
I gave Lemon the benefit of doubt even when he was weeks late and promised to deliver by the end of June (2 or 3 weeks ago), but at this point I'll just call it a scam.
