Not Reponding to logged call

On Monday 01-06-2015 I contacted Vodacom to complain that I do not receive my 100MB promotional Data each month. They investigated and indicated that I should not receive this. I told them that was what was agreed upon when I signed for the contract and that I did receive it for the first two months. They assured me that I did not. So perhaps I was mistaken, but where I am not making a mistake is that I have another contract taken out on exactly the same date for exactly the same phone where I do receive the promotional 100MB. They said they will log a call and investigate and come back within 24 hours. This is now almost 48 hours and no feedback was received. The service request no is S3-87D3J-J0ZTX.
