CLUELESS AGENT - NO ASSISTANCE

I bought 2 Nu Metro tickets from the vodacom voucher cloud app. I never received the second voucher number which was supposedly to be sent via sms. One other thing, i contacted the *** number and the agent was clueless and could not assist. what am i supposed to do with one ticket now? i am disappointed with the level of support you have for the service. It is useless and the mechanisms in place (if any) are not adequate enough for instances where the customer does not receive what they paid for.
