Vodacom 30-year competition

Vodacom 30-year competition. I received a phone from VodacomUnlockSummer, call to inform me that my number was selected, and I have won R25 000. I received a SMS with all the codes and pin to claim the money. I also received another SMS to state that I have won a Samsung Galaxy S21+. To unlock the prizes, I had to make a Donation to the Mandela Children Fund of R650.00 to get the prices activated. The next step was I had to purchases Vouchers from Blu to be able to withdraw the money. When I phoned Blu to find out about the vouchers, they confirmed it was used at Hollywood bets. Up till now I have not received any price and lost a lot of money. Well done Vodacom on 30 years.
