Once again - Disappointing Service

Once again, Vodacom has disappointed me. Towards the end of August, I did an upgrade on one of my mobile numbers. As part of the upgrade a R3500 voucher was included in the quote sent to me. On accepting the quote, I was informed that I would receive the voucher after the 1st Debit Order was received at the end of September. I called on about the 10th October to follow up and was told that I would receive the voucher on the 15th October. On the 18th I called again and was told that I would have it by the 23rd. On the 25th or 26th I called again and was told I would receive it by the 31st. I received it today at 18h36. Firstly, there is a huge error in the T&C's (see attached) and secondly, when I chose the Woolworths Voucher, I received a message that it was not available and would be available by 13 October 2023, today is already the 30th October 2023. I am mot interested in a Pick n Pay or Takealot Voucher. It appears that one cannot get anything smooth sailing from Vodacom. I should rather have canceled my contracts, which was my initial intention when contacting Vodacom a few months ago 😡 I wiould like send pics of the quote, extract from T&C's and message received regarding Woolworths Voucher
