Back and forth between FNB, Wesbank and eBucks

I am no longer getting eBucks benefits/rewards, and nobody can tell me anything straight between FNB, eBucks, and Wesbank. Each is blaming the other. Two cars and a home loan are financed by Wesband and FNB, respectively, and other bank accounts. I am upset with FNB considering interest and bank charges they are making from all of this. May somebody please investigate and help to get this resolved? At this stage, my opinion is that FNB does not care about it's clients and does not consider all factors and circumstances.
