Capitec service

I have been trying to use my capitec bank app from 3 in the afternoon to buy electricity and it was offline, I trusted it would be sorted out in a couple hours but not surprised at all its still not working at 2 in the morning. Almost 12hours later.I called and they said there's nothing they can do about it. And I am now sitting in the dark without electricity trying to find another way to buy prepaid electricity at 2 in the morning. This is unacceptable. I will be changing my bank very soon.
