Pathetic service with no resolution

Worst bank ever via the app, I bought electricity via the app from may having issues, every month I need to call nedbank to have voucher number sent to my phone, I then again bought electricity on the 27th of June till today nothing, I got a case number still nothing, till today nothing I had to call nedbank 5 times and still nothing, I did the chat service as calling was useless with nothing auctioned, I was advised it was sent to me the voucher number and yet nothing horrible service, IL never use nedbank ever again I'm closing my account worst bank ever
