From the sound of things I would say you are back to your old tricks again astana. Make a deal, negotiate something else, send funds to prove your "worth" then complain when the seller backs out from frustration.
I have done numerous transactions with shakaru and he has always been a stand up guy. You are leaving out details to help prove your case and attempting to force a trusted member to give in to your scammy ways.
Posting something like this knowing that you would need a large amount of evidence to prove to the community that you (a known shady character) got scammed from a trusted member is beyond me. This whole situation stunk of astana was soon as I saw it.
Good luck
Watch your mouth, you are warned. Old tricks? I'm probably straightest person on this board. Scam ? Go fuck yourself just for even mentioning that. Shady character? Prove it , name one deal where I have been dishonest, none. Infact I've paid upfront only to have douchbags and liars and cheaters and scammers fuck me. You little want to be btc judge, big words on the internet in real life well...
