Nedbank Data App a Failure and worse is their effort to resolve issue!

Tues 17th Sept I purchased R150 airtime and 1 Gig (R149) of data on the Nedbank banking app. I received 2 messages from Nedbank that my money had been taken off my account, but I was never allocated the 1 Gig, I did receive the airtime. I contacted Vodacom and they advised me that the problem was not on their side, but on Nedbank as Nedbank had not allocated the data. I have now called Nedbank 6 times since the 17th and have still not received my 1 Gig and no answer as to why!! i have chatted to Andiswa, Zainup and another Guy whose name I could not get. They all assured me that they will escalate my problem. Eventually yesterday I chatted to Chantal who advised me that non of the 3 who i chatted to had escalated the problem and she promised me that she would email her supervisor and that they will sort the problem out and she will call me at 4 pm. well I did receive a sms from Nedbank to inform me that they are still working on the problem, but no call as promised at 4 pm. So today I called again and spoke with Londo who says that Nedbank has now emailed Vodacom to see what the problem is. I told him that i did speak to Vodacom on the 17th and they said the problem was not from their side, but he said he cannot do anything and that there were no supervisors available as they all leave at 4.30 pm. I am running a business and need my data. One says that the problem is with the actual Nedbank app, the others cant tell me what the problem is. I am really not impressed with Nedbank at all. This is really frustrating and i would really appreciate it if someone can sort this problem out as Nedbanks employees do not seem to know what they are doing.
