No 30 Gig Data

We opened a new contract in the beginning of April which stated that I would get a free 30 gig data. To this date, I have not received this data. I have tried numerous times to call and we we are being sent from pillar to post. We were told it would be done within 24 hours, then that it would be loaded the 27th, we were given a reference number and assured that it has been escalated and that it was captured incorrectly. Ref 1- ********** 6779. Still no data ? No Feedback No answers. Tried phoning again this morning only to be given the run around again. My husband has been a loyal customer of yours for many years and after the bad service received from Vodacom I decided to switch over. Now im starting to wonder if I made the right decision, cause surely this is breach of contract ????
