Vodacom is a ***** that should be taken to court

I bought R100 through VodaPay via the MyVodacom app. There was a goal to get 65 Vodabucks if I bought R100 airtime through Vodapy. I received a receipt from Vodapay but still no airtime or Vodabucks!!!! I called. sent numerous emails, was told on messenger that they cant help me. Its been almost 3 weeks now. I want my money!!!!! Vodacom is clearly ******** people and *****ing money. This is theft!!!!!
