Poor problem handing and feedback.

Admittedly first problem encountered using the app hower resolution is non existant, bought Data via mobile app, data not loaded but account debited. Called MTN who directed me to FNB, logged call with FNB who investigated and a week later automated response of "airtime successfully loaded" received, this is not acceptable as l still have not received the data, calling for follow up you get put on hold for over 10mins.........use the app at your peril.
