Immediate payments

I have made an immediate payment on my mobile app to FNB over an hour ago and the payment has not gone off from my account nor has the recipient received it.

I understand that I will be charged a fee for making this type of payment, however, I dont feel it's fair to be charged as your company is not sticking to their promise of immediate payment

I have been having problems with over charging on bank fees from this company for years and now this ?

I'm officially done , taking my business else where.
