Really poor service from FNB!!!!!

Recently I filled up my car. My card declined with insignificant funds, however there were more then enough money available. I was charged R8.50 for this.

I have spoken to my branch who advised me that this was a mistake from the vendor and not their fault and won't refund me and that I need to speak to the vendor.

I have laid a complaint with FNB online and was suppose to be contacted within 48 hours. more then a week later I finally received a call from a call center agent who was extremely rude saying that this was not FNB's fault, which I do understand.

I however don't think its fair that I have to pay for someone's mistake and then receive this treatment from a bank where I have been all my life.

Really really poor service from FNB!
