MTN unable to load data component of contract

I renewed my MTN contract on the 26th August 2018, and every month I have to phone MTN and send multiple emails to get them to load the 20 gig data component of my contract. They always say that according to them the contract does not indicate 20 gig data. I then have to send them the contract details to which they respond by loading the said 20 gigs of data. Why do I have to do this every month? At what point do they correctly load the data component of my contract so that I receive my data? Why do I have to send them the same contract information every month? I have been dealing with Jabulisile, Noxolo and Eugene and nobody knows what they are doing! I’ve kept all the emails and will go to the media with this problem do show MTNs incompetence if it is not resolved! This is very unprofessional.
