U are getting refunded for that bet , ur bet + profit u would make. And that is it.
U can't get refund for any bets before or after that .
If he always martingales, always doubles after losing a bet, then I don't see why you wouldn't refund the whole losing streak that followed the incorrectly settled bet. It's pretty obvious that he wouldn't have gone on to make all the bigger bets if the incorrectly settled bet had been marked as a win like it should have been.
The error is entirely PD's fault, and in a clear cut case like this I don't see why they wouldn't do what's right and refund the whole losing streak.
It seems pretty unlikely that either of his buggy rolls were part of a busting streak anyway, so it's probably an academic point, but the attitude I'm seeing from the mods quite frankly sucks.
