Promotional data not received

On 3rd April I took my gravely ill dad to MTN Fountains Mall Jeffrey's Bay in order for him to upgrade his contract. He was advised that he will receive his promotional data within 2 to 24 hours. It has now been more than a week and still no data! Every time I call the consultants (Clinton and Nathan) to follow up, I'm told the matter has been escalated, or that their system is down and they cannot assist. This is unacceptable and false advertising. My dad could've taken out a contract with one of the opposition parties who deliver on their promises timeously.
