Powerball winnings not paid

************* bank. Played powerball on the 26th of December and won some money. I played the daily lotto as well on the same day and they paid out the daily lotto winnings because it was R5 and R10. But the powerball winnings are nowhere to be found. Next day I checked on the standard bank app, and suddenly there's no history of any powerball plays, yet I have the sms stating I played, the amount I played and the winning numbers. I called and they said I should speak to the Ituba national lottery. So why didn't I have to speak to the ituba national lottery about the R5 and R10s that I won? Because it's chump change. Yet when you win a few hundreds, they remove your powerball history and make as if you didn't play. But I have the proof via sms. I emailed them as well as the ituba national lottery and I've yet to receive a response. They have no problem taking your money but as soon as you win something they become *******s. What's crazy is I changed to standard bank in this month. Biggest mistake. I'm going back to Capitec.
