Betwinner Casino - Bonus winnings cancelled

Hi,
I created account in Betwinner.com and make a $100 dollar deposit then they give me first deposit sports bonus. I wagered full bonus according to their terms and did not even breach a single term. After wagering bonus, 100 dollar bonus money added to my real balance. When i make a withdrawal request they demanded from me identification verification. I provided everything and completed process of verification. After that they said me specify your relation with these three persons. They randomly make a reason i don't even know any of those person. I said i don't know. They said you did a bonus abuse. They ended my bonus money winnings. Please it is my request take them my hard earned 100 dollar bonus winning. I did nothing any abuse and did not even violate any terms. When i asked to provide me a proof they did not provide and did not giving me reply of my email. It take me almost a week to wager the bonus and when i successfully wagered it they ended my bonus money. Plz give me my money
Thanks
