Vodapay unacceptable service and resolution time

Vodacom / Vodapay. Bought a R800 BP Voucher - the amount went of from my credit cards and on the Vodapay app it indicates that Payment successfull. However. I did not receive the voucher and it is not reflected on the app under vouchers. When following up, with Vodapay, the consultant Lenny said that it shows as pnding on their side. He must escalate and it would take 4-7 working days to resolve. If their own app states Payment successful how can it take 4-7 working days? How can you trust an app behaving like this? 7 Working days over the easter weekend means up to 11 days. To amke it worse, Lenny said that they would sms me a refernce number - not recived. The transaction was successful onthe Vodapay app at 12:16 on 28 March 2024.
