Vodabucks

Vodacom sent an SMS stating that i will receive 800vodabucks if i buy electricity or pay DSTV. I did that and received the vodabucks yesterday. Then when am trying to bank them am receiving this on app " We're experiencing some technical difficulties please try again later". On ussd is "An error has occurred please try again later". I have called the call center and even chatted with Vodacom on Facebook. All i have received from Vodapay agent was "maybe you bought the sim from the street " and he hunged up the call. Eventually Pinky the customer care consultant managed to logged a case and she said it'll take 7 working days to be resolved. I wanna know how will this work as my 800 unbanked vodabucks will be no more?
