Poor Service, No data allocated, No Feedback

As a long standing Vodacom contract customer, I'm at my wits end with the appalling service that I have recently received. I purchased 1G data to supplement my data allocation and received a confirmation of the successfull online purchase from the Vodacom website on Friday 24 July 2015. However, up until today, 27 July 2015, still no data is reflecting on my account despite my purchase confirmation. I have made several calls into the call centre, but having spoken to both Palesa Mthombeni and Robert Mphshaphuli on 24 July 2015, the problem is still not resolved. All the while, Vodacom is now charging me exorbitant out of bundle rates despite still not allocating my 1Gig of data which was previously purchased. Reference # for my complaint is S3-8BSCN-NS6V. Reference for the purchase of data which was never allocated to my account is Order #: E***. It has been very frustrating dealing with Vodacom as the call centre staff are absolutely useless and cannot resolve any sort of query. Moreover, they do not seem to be focused on assisting customers and simply say that someone will come back to me, which does not happen until I call in once again. Please resolve this matter asap.
