Black Friday Data Promotion Still Missing

I signed up for two new contracts during the Black Friday weekend. As part of the BF promotion customers were promised once off 50GB of data which was valid for 7 days. I was advised that the promotion only applies to one of my contracts since the other other one was not a BF special. I was advised that the 50GB would be loaded in a week- this did not happen. It is now two weeks since BF. I have made several visits to my nearest Vodacom store. The staff at the store logged a service request on 28 November . I've been given the run-around for the past 2 weeks. I went to the store and they said they will log another request. I am tired of this. I dont see what the difficulty is.
