Miscommunication unfair no solutions to mystery prize reward won

I can say I'm very disappointed by vodacoms actions towards unlock summer reward.on 18 Nov I played and won a 1000 bill settlement, on 24 Nov I received sms saying bill settlement won will show on my next statement. On 7Dec when I logged in on my vodacom app I was very surprised to find that I was loaded with a 1000 airtime instead of bill settlement. And there was no communication here.i have tried calling vodacon several times all I get is from the 8thDec that they were only told on 8th morning consultants that 1000 was loaded to top up contract customers due to the nature of their account.frst theres no communication,secondly we get sms after we started calling vodacom trying to get answers of what happened to 1000 bill Settlement here instead we stuck with airtime that we don not need. I myself do not need that airtime...allim asking from you is to please reverse back your airtime and give me my prize won .
