You could say it’s more of a glitch than a shady tactic and I already knew about the bonus amount not being withdrawn after reading the T&C. But after I did their verification (which was fast for me) It subtracted the $200. Only thing I could say is possibly fix the wallet amount displayed? In my real balance it showed $300 after I won depositing $100 and I used the 200% no rules deposit welcome bonus and nothing in my bonus balance.
I got my pay out and withdrawal was legit.
