Vodacom Service Delivery is completely and utterly useless

My wife upgraded her contract in late Nov 2020, and part of the deal was a R3000 Woolworths Voucher, to be delivered in 15 working days.

It is now 27 March 2021, and despite consistent complaints, questions, and other communication, and even numerous Hello Peter Complaints - the only response from the "mighty" Vodacom is that the query is in hand, and we need to have patience. It is the same response EVERY DAY - please be patient. NOTHING ever happens - Vodacom likes to lie to themselves that they've "responded".

Vodacom's response to the previous Hellopeter Complaint: "We are sorry to hear of the circumstances under which your posting has reached us and we do apologize for the inconvenience caused. Our records indicate that your query is currently in hand with our Hellopeter Team and they have escalated the matter to the relevent team. We have requested the team to prioritize and provide feedback. We apologize for the inconvenience and appreciate your patience." Yet still - NOTHING has changed at all! No resolution, only requests for patience - 3.5 months after promised delivery of a mere voucher.
