I hope Stake can still solve this for me. Does not have to be by re-grading the bets but just a manual bonus credit of the missing winnings would also do. There is always a way.
they told you that the problem was on the side of the odd provider, so they can't be held responsible in this matter, I think it's common sense.
you are already being answered by Steve in this scam accusation thread, it doesn't make much sense to take the discussion to this ANN thread as well.
