Betta Bets are ****mers

Worst site ever. Ibsigned up and played with their R187 free bonus play. I won R6300, to withdraw they told me to deposit R350 which I did. After depositting R350 they told me I needed to deposit another R550 to bring it up to R900 (VIP2). I have all the screenshots where I confirmed that after the R350 i would be able to withdraw my winnings. These ppl are a bunch of ****mers!!
