Vodacom failed to load my 5G and 500min for Dec month as per my contract

Vodacom failed to load my 5G and 500min for Dec month as per my contract. This is so frustrating. Every month there is something wrong with my contract. Not sure why this is not auto loaded every month and done right the first time. This is probably my 10th complaint with Vodacom this year alone in less than 4M since i upgraded. I called the retentions department yesterday and spoke to 2x different consultants who promised to resolve and i still sit without the data and minutes after spending almost 2 hours on the phone for nothing. Please resolve this issue asap.
