Unused data depleted.

I loaded R40 airtime and I used that airtime to purchase 1 day uncapped data. Then got to texts fr<br> MTN telling me my data was successfully loaded and another telling me that my data has depleted. I spent more than 30 minutes with consultants on the phone and I was told I must wait for next month to find put what happned. I think this is ***** and the MTNs inability to give me a proper response to this showed the level of incompetence in this company.
