I want my 37 vodabucks back

On 16 Aug 2026 I loaded airtime for R19, my balance was R21-44 (I had balance of +- R2-00). Then I purchased 100 VC minutes for R8-00, meaning my remaining balance was R15-44. On 17 Aug 2026, I purchased All network unlimited minutes (500) for R13-00. To my surprise I saw an sms saying: "Vodacom: You've spent 37.0 VodaBucks. To view your VodaBucks balance, visit VodaPay: https://vodapay.go.link/eoziO or dial *133#. T&Cs". When I purchased 100 vc minutes on 16 Aug 2026 I followed this steps 1. Buy, 2. Voice, 3. Until midnight, 4. 100 vc minutes R8-00 (Just 4 You), 5. Choose your payment method, 6. Airtime, 7. Buy now, 8. My 100 minutes were loaded though they expired midnight. There was no option saying I am buying minutes using airtime + vodabucks. I was not diaclosed, why then tell me I used my vodabucks, aowa. So now vodacom took airtime for R8-00 and stole my 37 Vodabucks.
