Vodacom really disappointing

Vodacom is busy making empty promises with the shakeup promo. They say every time you recharge, you earn vodabucks, which you can purchase products with. Last week Thursday I bought a microwave on the app, and they just sent me an sms " HI :) we have received your VodaBucks Store order. Your order confirmation will be sent via SMS during the course of the day. They never updated me ever since. I called the customer care, and they sent me another sms, saying the case has been closed. Then referred me to digital planet, saying that I must call them. Digital planet knows nothing. I have been blocked from the Vodacom customer care. The microwave cost R1390, with my vodabukcs. Been a Vodacom customer since 2000 and this is the reward I'm getting from them
