airtime not converted to data

On Tuesday morning(8/12/2015) between 7h20 and 7h30, I purchased R50 airtime from my bank. I then tried to buy a weekly 500 MB data bundle for R45. The airtime was deducted but I didn't receive the data bundle. I called the call centre and was asked to patient because the system would update later during the day. I called again today and I was told that my query has been escalated. How complicated is it just supply what I purchased? I needed the data yesterday but now have to beg Mtn for what I paid for. If you ask me Mtn have become very ***********. Now I understand why Mtn is in hot water internationally. If I had my own way, I would multiply their fine by a million. It's the second time in three months that I have to complain about Mtn. Something rotten is going on there. Is just me they are targeting or everyone is suffering at the hands of Mtn? Please help me get my R45 back! The affected number is ***.
