Dosh
I got hit in the Dosh / ODOM massacre last year with about $60 stranded.
Dosh told me the only way to get the dollars was if I did 57 non-GC transactions over 19 weeks.
I figured it was a lost cause, but I tried transferring the balance a couple days ago and it worked.
This may be widely known, though I didn’t see anything when I searched the thread.
