VERY DISAPPOINTED

I bought electricity with my nedbank banking app in the morning and I did not receive any notification with my token. I called the call center and they advised that they logged a claim and I will receive feedback within 3-5 working days. I don't have electricity and i was told there's nothing that they can do. Now the banks are closed and i don't have electricity. I tried logging on to my internet banking profile and currently is blocked and i should contact Nedbank call center. When I call, I was told that there's nothing they can do. I should spend the entire night without electricity. Im very disappointed, maybe its about time i change banks.
