****med by world sports betting

My daughter was registered on world sports betting by one of their agents on 30 September and was given r170 bonus lucky for her she played live games and won now instead of paying her winnings they said she needs to wager r250 that is 5 times r50 she did it now they are coming up with a story that her account is linked to the other account and they won't pay her they closed the account why didn't they find that all along only once they need to pay they are saying that I believe that they are ****mers. Please help us expose them and get my daughter's money back.
