Telkom mobile's arrogance and horrible service.

I bought data via my banking app, I then got a message from my bank notifying me of the transaction and that it was successfully bought. I waited the whole day for my telkom mobile data to be loaded on my phone. I then decided to call the customer care number to tell them of this problem, I was told that they are having a general problem with the banking apps and that I should wait for 24hrs for my data to load. I waited 24hours and still no data. I called again they said i should call my bank and ask them to reverse it. I called my bank and they said they can't do such a thing. Telkom must sort it out. I called again and they said I was supposed to go to the police station with my bank statement that shows the transaction and write an affidavit sayin that i bought data and it didn't arrive, basically proving that I bought data them call again and they will tell me which email address I must send these documents to. I find it disgusting and arrogant of telkom mobile, why are they making their problems mine? Why is the onus on me to prove that I bought data from them?
