Last week I received a letter from "Banco de Portugal" wich regulates bank activity, saying that my bank had no action and no responsability on the funds taken by betfair. So I suppose 2 things:
1- Betfair just charged it back and legally they can (?)
2- There´s something strange behind this... I mean really strange (€)
So, they are saying that if a company has your bank details, they can "charge back" a sum they have paid into your account without fear of reprisals.
This is obviously a loophole in the law, and probably one that has not been used in this way before.
Maybe you should try to get the media interested in this position on the matter stated by the regulator, and how this is a loophole in the current rules that can be misused by any company that has your bank details, and the customer has no right to expect to be asked for permission.
This story could make the general public worried about the wider implications of this, and thus demand a tightening of the rules.
Maybe Betfair knew that they could do this, and get away with it. They also took 8 months to return the deposit, and since their decision was "final", why did they NEED a further 8 months unless they intended to act in "bad faith" and keep as many DEPOSITS as they could, as well as confiscate winnings.
In hindsight, you could have beat them at their own game by moving the 32K out of the account as soon as it hit, then they couldn't just have taken it, but would have had to present a case for it's recovery, even take YOU to court to prove that you didn't win it. They could easily have lost the case, since you didn't break any of the terms, and they paid other players in the same position, so were trying to selectively not pay players, rather than applying the rules fairly to all.
It is possible that many players have given up the attempt at taking them to court once they had found out how much it would cost, and how hard it might be to win the case. If they lost, they would face paying the costs of Betfair on top of their own, and this might have been enough to scare them off.
Betfair now have far more to worry about than this issue, as their shares are in "freefall" because of poor performance since floating on the stock exchange. I expect ANY negative publicity over this will encourage them to look again at this issue, and this would include a media storm over them arbitrarily dipping into your bank and taking the 32K that you won WITHIN the terms and conditions.
