Worste site ever

I received a R50 bonus, from that I won R300 which I was able to transfer to my main account and from that I went on to win a further R7000. Now I'm unable to withdraw my winnings, I'm told I need to deposit R100, which I did and still my withdrawal is just awaiting approval. Do these people even have money or are they running a **** here. Stay away from this site.
