Bought Data bundles via Internet Banking

I bought data bundles of R149 via internet banking this morning and the purchasing went through as it debited on my account but it did'nt recharge on my phone. I called MTN to enquire about this and MTN told me i need to speak to Nedbank as the problem is on their side, I called Nedbank to enquire about this and they could see that it went through but now they telling me they need to contact MTN to get voucher details from MTN for me so I can be able to recharge and that would take 3 to 5 working days for me to receive my voucher :( . I mean why is it that i have to wait for so long to get my voucher to recharge when the purchase went through, i cant buy data today and receive it after 5 days it deosnt make sense to me,and it angers me that i have to go through this when i use one of their services of buying airtime via bank which is supposed to make our lives easier but instead is doing the oppossite. For crying out loud I bought this data today cos i need it today. they making their problems client's problems. I cannot suffer because of their system failures. I logged a complain with nedbank and still havent received a call from them to address the issue.
