Capitec Immediate payment ****!!!!!!

I had a urgent transaction that I had to do from my Capitec account to another bank so I used 'immediate payment' option but the funds were still not reflecting an hour after doing the transaction, I then took the initiative to call the customer care centre and the lady that I spoke to had a nerve to tell me that even though I have used 'immediate payment ' option it will still take 6 hours to reflect...I mean how ridiculous is that?? What does 'immediate' mean and why did I get billed for that immediate nonsense if its actually the opposite???? And the nerve to tell me to wait 6 hours??? What **** is that??? So immediate payment means something else at Capitec??? DO NOT INSULT ME AND GIVE ME A PATHETIC SERVICE AND STUPID EXPLANATION FOR IMMEDIATE PAYMENT CAUSE ITS SELF EXPLANATORY!!!!
