No data or SMS bundle credited

I am now in the second month of my contract and no data or SMS bundles have been credited to my account. I have only received minutes.<br> I am on My MTNChoice 200.<br> I have been to the store on numerous occasions to try and rectify this issue but they always tell me to wait a few days to see if my account does get credited and then come back. I have had enough of wasting my time.<br> It is totally unacceptable that I have to pay for extra data when I'm supposed to actually receive data from my contract. I should receive what I pay for and I don't understand the difficulty in doing something so routine as crediting data and SMS bundles for a contract.
