FNB Call Centre Provided the incorrect information and now unwilling to help!

It’s been nearly a year and FNB is still playing delay tactics and unwilling to help! A payment bounced back and a FNB Call Centre Agent provided me with the incorrect information (the wrong person), which lead me to making a payment which would have never happed had they given me the correct information! The person is now refusing to refund us the money and FNB is unwilling to help with getting the R30 000 back. My Business Manage Heinich Cupido sat with me while we listed to the call recording of the call agent providing me with the incorrect information but has been unwilling to provide any accountability and assistance! FNB should be assisting as this was their mistake!
