MTN data bundle migration

I received a phone call on Friday 12 April 2019 at 11:05 from the direct sales team to migrate my contract and to add an additional 1 gB data bundle for an amount of R93 pm. The additional data was suppose to be added to my contract within 72 hours. It is been over 144 hours later and no additional data was added to my contract. According to the direct sales team it was done on their side. After 7 transfers between consultants at the MTN call centre I still could not find out the reason why it is not done. I would like the data to be added to my contract as soon as possible, otherwise I will cancel the additional data bundle.
