Supabets is robbing me what must I do !!!

Good day I would I to start by saying supabets is robbing us people . They have an investigation going but they are still taking our money when we deposit. So how can their still be a problem or investigation going on about the free spins . I never knew about the free spins so I deposited money into my account played nd when I opened my agt games I received daily free spins. Remember I deposited money first they can check on there systems nd I won R11000 . I withdraw a R2500 nd a R2500 by standard bank and then I withdraw a r7000 by supabets. I received the R7000 bt I never received my R5000 so supabets is robbing us nd when I tried calling them they just put the phone down in my face .
