Vodacom contract - Do not receive airtime or data I pay for.

I took out my very first vodacom contract. R749pm was suppose to get data and airtime with contract. My money gets deducted, but I don't get my airtime or my data. The store keeps telling me that they can't help me, I need to phone vodacom customer care centre. Vodacom customer care keeps telling me the only sort out online and telephonic application errors. The number and the address on my statement is incorrect. I am already due for an upgrade in November and still no help. I am not going to let this go. Can anyone recommend how I can get help please. I paid for my data and airtime, I want it!
