Dirty network doing shady thing's customers are unaware of

For the last 4 days now that I have participated in Vodacom's mini program/promotion unlock summer, I have received the exact same rewards ... So I don't understand why they would run a promotion to unlock summer & win vouchers/airtime/trip's, etc when they are actually ****ming their clientele .... It's actually disgusting to have noticed the ********* disrespect from a major mobile network generating the amount of money they profit from. I have screenshots &. Emailed history of rewards, common ethical practice would be for someone to respond to me .... Soon.
