Gold rush bingo

Get this. They advertise 50% deposit refund, so when I basically trippled the refund amout on the game, the took my initial deposit amount, to give me the "refund" back, what the hell??? I tried to check my transactions to see what happened, and conveniently the last half hours bets is not on it. Bunus my ass. Please people rather try a different platform, it is ********. All because it states so in the terms and conditions wth? It is like a bank saying if you save a R1000 a month for 12 months, they will give you 50% back, and at the end of the year they give you R6000 and keep the rest.!!!
