I don’t want to post their names here but WC, SB, and others, have a long, long, long history of being unethical. For what its worth they are as crooked as they come.
I highly recommend that you do some research especially prior to selecting a partner. It wouldn’t take long to find out about such operations, do a search on Google or better yet post a question here on CAP you are sure to get an immediate answer.
Remove their links at once, dont send them another player! Trust me if they are refusing to pay you now, taking down the links isnt going to make a bit of difference, they are crooks!
