I got 0.1 btc (still to confirm) so far I think I'm owed 0.3 in total (looks promising anyway)
Transactions are sent by exact amounts of deposits. So if you deposited 3 times 0.1 then you will receive back 3 times 0.1, this is done to be more precise with the refunds. Be patient for 24 more hours until all the refunds are processed.
In which order are you refunding? The last who bought will be the last that will be refunded?
