Betfair account suspension help?


So i won around 200£ in profit on their live roulette and due to the stakes I was putting down I withdrew around £600 over 3 withdrawals in one day. Then a few hours later my account had been suspended and after using the live chat they said I had to send proof of id and address to a ladbrokes email for a chance of reactivation. What are my chances of actually receiving my winnings and all the money I put in??? I am quite concerned as this hasn't happened to me before.
If you provide them with proof of ID they should re-activate your account - they'll expect you to plough all the money back !
