FNB not refunding for invalid electricity token

I purchased R450 worth of electricity via the FNB mobile app on 01/10/2017 and the token I received was rejected on my meter.

The can be no error on my side as I just repeated a previous purchase and the reference number I saw on my transaction history shows the correct meter number. This could only be caused by a system error. I've used this service on a monthly basis for years and this is the first time i've had an issue.

When I called premier banking I was told that their is nothing they can do as they only provide the service and hung up! I've also messaged premier banking via the FNB website and still awaiting a reply. This is pathetic as I purchased the electricity via FNB and they should at least ensure their service works or don't offer it in the first place.

Get your act together and don't make your customers suffer for your system errors!
