Vodacom ripping me off

yesterday I bought airtime and data bundles and got messages from Vodacom confirming that, but when i checked my balance was reflecting zero on both airtime and data bundles. i called the call center and was told the matter is being referred to service center, and they will get back in 24 hours time, today i called to follow up i was told that anyway this due to be closed on the 21of September which is way more than 24 hours. and I asked what must i do in the mean time i was told i must recharge again how can I recharge again must i recharge so that my data and airtime to be ******. I am very disappointed with vodacom with service i receive from them i have been a loyal customer of Vodacom and this service is very very poor
