Missing Airtime

Good Day, I purchased a R50 cell c voucher via the Nedbank Money App on Friday night the 28th September. And I was charged on the 29th by my bank. But on my bank statement the transaction reflects on 01 October 2018. Which is something I really don't understand.

But my main issue is that I am still waiting for my airtime from Cell C network even TODAY!! I contacted Nedbank via the app and was advised that I must contact Cell C because airtime was sent through to Cell C. But for unknown reasons, it was never credited to my account!! I contacted Cell C and was told to send all the supporting documents which I did. 02/10/2018. And ONLY on the 08/10/2018 Cell C sends me sms saying I must contact my bank to log a case.. Which is absolute *******!!! Why was I asked to log a claim in the first place? !! I need this to be escalated!!!
