FNB failing consumers

Got a call from FNB this morning, regarding my query and their response was truly poor, felt they didn't read nor make means to investigate my query. All the lady could tell me was the name of the company which I specified I got myself last week when I called the company to reverse my money. She then also said I need to call the company myself and its not FNB duty to do so!!! What's sad and poor about the service I got from FNB is they didn't even bother calling the company that took my money without any signed mandate. I guess I must I must accept this is the poor level of customer service we get from FNB and I must accept I just lost R4000 just like that. I think best thing to do in such a situation is find another bank that will provide a better service because honestly FNB has failed me.
