Cannot get data added. No Help of any kind!!!

I ran out of data so phoned in to get an increased limit. After 3 to 5 calls confirming it has been increased telling me I have about R56 i can use I still cannot buy a data bundle. Not using the 147 options nor using my online banking to buy data for my account. No one can tell me why. its always an excuse, system, or restart my phone, or wait 15 min. The last guy i spoke to said I have about R9 left. How. WHY!!! What is going on!!!!! no one can respond. Trying to lodge a complaint or help of sorts on the cell c site but no options for complaints imediate help etc. Ive been in urgent need of data since 15:30. its now 02:00. Still cant get data even though its been confirmed by the 3-5 call centre agents i have the limit increased with money to increase it. Any data increase i try do fails!!! Why!!!
