Data not loaded (60GB+7GB) worth R598 all together

On the 1st of September around 04h00 am, I bought data: Sevendayeverydaygigs 7GB worth R99 + Thirty Day EverydayGigs 60GB R499. Both data was never loaded.. I called MTN call centre on the 1st and I was told they moving me to the new network, I need to switch off my phone for 5 minutes, then dial136 to check the balance. I did that, no data was loaded. I called the call centre again, then I was told even though they can see the airtime that was never loaded to my phone, IT will resolve this within 24hours and was given this *** . To date I have not received my data. All I want now is to have my R598 spent when buying data that I never received. Sadly I have been a loyal customer to MYN even though they constantly deduct my airtime for ko reason. But sadly MTN has gone too far by not loading my data which makes me question their integrity.
