I've been having a ton of diffculty with bitshadow these past couple days. My money vanished, and they seem to have stoped responding via their safe-mail tho it is still fairly recent. I really do hope this is just a glitch in the matrix and nothing fishy is going on, but you never know.
Never heard of them personally, why do people insist on using shady tumblers/exchangers that seem to have no sort of valid reviews. You likely got scammed, or I could be wrong as I haven't moved away from Grams for a while. You should use services verified in the sidebar of the sub next time to avoid this happening.
