Data not loaded but money deducted

I used the Vodacom app to buy 2x 5G data for another number. The data was never loaded, but yet Vodacom deducted the money from my bank account. I have been struggling now for about 2 weeks for either the data to be loaded or the money to be refunded. Absolutely pathetic service. No one gets back to me. Was initially advised that it will be sorted out within 72 hours. Currently more than 240 hours. I will never use the vodacom app again.
