Vodabucks not earned even after numerous calls

When completing vodabucks tasks nothing was earned I have spent so much money and no Vodabucks. When calling the consultant said these had been allocated which is a lie as I have the history on my Vodacom app and nothing has been allocated. Please sort this out as I find this very unprofessional and I am very tempted to cancel my contract and move as I feel as though vodacom is *****ing my money and not loving up to what they are advertising. To add my query had been escalated as per SMS then closed as the consultant said it was allocated when it was not.
