FNB cannot Help You

I made a payment from my FNB account to another FNB account and 24 hrs later it still has not cleared. I have lost R300 on airtime calling the call centre, no one can assist me as the say the money is processing yet on my online banking it reflects as successful. I have been transferred without being assisted 12 times from one department to another one of which claimed they had sent proof of payment to my email but the email i still did not receive. When i called again the last agent i spoke to transferred me while i was still talking. I have had to cancel my purchase because the supplier will not render services without POP. Thanks for nothing FNB, all i was asking for was Proof of Payment and an explanation of where my money is and i got a slap on my face!
