MTN daylight ********

I had airtime and bought data so that I serve the net. I struggled with network and it worked after +-30min. When I was done using the net I checked my balance only to find that my airtime was chowed instead of data being used. When I called MTN their excuse was that my " out of data bundles" settings were on. I went to check on that only to find that they were long blocked and I have no other subscriptions. I had R120 bought R17 week data of 120MB only to find myself with R47. I called them twice and still received no answers to what really happened to my airtime as I believe out of data bundles work exactly when you are out of data.
