Misleading the public with Play Everyday

Vodacom Play Everyday awards free airtime to any any network, confirmed by SMS received from Vodacom, only to charge the unsuspecting public when attempting to redeem the free airtime, claiming some sort of mismatch between the Vodacom system & the Play Everyday system. Vodacom Customer Care rather unhelpful & the consumer foots the bill for what appears to be unfair business practices, falsely enticing the consume via SMS to use the network, under the impression that they won free airtime, then charge for it. Wonder how many others got caught this way & how many extra unsavoury millions went into Vodacom coffers as a result?
