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.
It is just too easy to hide behind an odds provider. I am dealing only with Stake, I'm not even allowed to talk to this odds provider even if I wanted.
The fact is that these odds were not (clearly) wrong and if they start to void bets like this, then any bet is in danger?
They might start voiding bets on Barcelona when you bet on odds 1.25 (sorry, odds provider made a mistake, they meant to offer 1,24). Stuff like that, it's absolutely rediculous.
If it was a pre-match bet and I would still have the chance to place the bet at another bookie it would be a different story. But voiding a live bet after it had 99% sure won, is insane and filthy.
Stake might not be the one who made the initial mistake, but they are the one resposible for the decision as they chose to deal with that provider. If it's too difficult to still change the bet status then they should solve things in another way, for example by crediting a bonus of the missing amount.
Who is Steve in that accusation thread btw? Is he this person "Acroman08"?
