Unable to process Credit / Debit Card refunds to FNB Clients on a Nedbank speed point machine.

For more than a month now I have been complaining to Nedbank Card Division as I am unable to process refunds on FNB Cards on my Nedbank Speed Point. Due to the nature of my business I need to take deposits for items that I hire out. The inability to refund FNB card customers on my speed point means that Nedbank it literally, “smiling all the way to the bank”, as they charge me a fee for the initial transaction, then a 2nd larger charge on my cheque account when I must manually refund the client for the deposit held. Nedbank keeps on blaming FNB, however, I ended up also complaining to FNB and they need an incident report reference number so they can look into the problem and investigate why this is happening. Nedbank still can’t supply me with the reference number although my query has been investigated and escalated numerous times! I am now tired of constantly phoning Nedbank to try and get this issue sorted out. Will Nedbank actually refund all the FNB Bank charges when they do eventually sort out this issue ?
