Vodacom

I just signed a new contract with Vodacom, which is 10gb and 100 minutes. When I called in for the contract I specifically said I wanted airtime and data and I was told I can only get minutes and I asked how the minutes work and she told me they work just like airtime and I was ok with them contract completed. Comes end of the month I only receive my 10gb with no minutes, I called in to ask why I did not get my minutes, they told me the contract does not include minutes, I asked why because I specially stated that I needed the airtime, and no answer was given and was told a person by the name of Letchie Ajoodha was gonna give me a call up today, I have not received any call. Am very disappointed with Vodacom really
