well from your story im pretty suprised what you won with your starting amount and as they are proffesional and they wont just give you money (i dont know if you heard about hufflepuff) so i think its normal that they check everything about your bets and check that you didnt find a way to bypass the system give them some time and as soon they verify that all is legit they will w/d your funds
