Not impressed with disappeared data

I loaded data via the mtn-active website like I have been doing for years without any problems. This time, however, it is a different situation. I loaded 1 gig of data on the 30th of August 2017 at 18h30. it usually comes through straight away. After 15 minutes of waiting, I phoned the call centre, in which the response was that it takes 2 - 24 hours for the data to load and that it is a network problem. I have at the same time loaded data for my daughter's phone, which had gone through immediately, but not the data for my number, although it stated that it did according to the service report. I phoned again the next morning. It was said that it must be "overrided", which means it will be another 2-24 hour. I phoned 3 times again on the 31st, receiving the same response: that the transaction relects on my unbilled invoice and that it is pending, it will take 2 - 24 hours. I phoned again on the 1st of September and was advised to wait till 10h00. No data yet. I phoned again and spoke to Malick who referred me to the technical department who then just referred me back to customer service. This is like running around in circles. I am going to pay R160 for data that was not loaded on my phone. I do not think it is worthwhile to contact the Mtn complaints department as I feel I will just be sent from pillar to post.
