Risky

I have lost R50 000 with a tennis match where the player already retired and my stake of R50 000 should be refunded. The cashout went through about 1 minute after the player retired. I have watched the match live. Why on earth will I cashout a match when I saw the player my bet was placed om was busy losing and have retired. Then my money get refunded. They claim there is no evedince that the that the cashout went through after the player have retired. I jave streamed the match but I have lost a stake of R50 000. A manager named Michael thinks World of Sportsbetting is his. He make and brake like he wants and nobody do something about it
