VODABUCKS is a ****!!!!

I used my vodabucks and my money to buy a nando's coupon after a vodacom consultant advised that I would be able to use the wimcode on Mr D or Uber Eats. When I received the wimcode, I realised that it does not work on either of the platforms. I requested a refund and was told that I would receive my money and the spent vodabucks after 7 working days. After several calls and escalations, this has not happened, order number is 801791, I want to warm customers to refrain from using the vodabucks store, especially if you will be using some of your money to top up on your vodabucks.
