Didn't inform me of a promotion & never available

I received an upgrade on my MTN contract on 10 January 2016. On 10 February 2016 I received an SMS letting me know that the 30GB of free MTN data for the promotion that was running for upgrades and new contracts had expired. I was never informed of this promotion when I received the upgrade, so did not know that I had the data available. I did not even use 500MB of data during the same period. To make matters worse, the cell phone that I received on 10 January crashed after 8 days and had to be sent for repairs, so I was without my new phone until 28 January. <br> <br> I went into the store at Fourways Mall shortly after receiving the SMS, and they told me that they would contact the head office to find out what the status was. They didn't ever call me back, and I have tried to call the store almost daily for the past month. The call has never once been answered.<br> <br> I am fed up with the lack of communication and would like to know if anyone else has been given the 30GB of data without being informed that they had it.
