Bad Attitude and pathetic service

Most terrible serviced received from a bank, i had logged into my account and to my surprise had seen a large amount missing when checking on my statement i have noticed this had been charged as handling fee R3128.00. As the weekend been a holiday today i called the call center and the agent had a terrible attitude when i had asked him to explain the charges to me, i know and understand that all banks have charges on 1 day i had made 2 withdrawal the teller had not bothered advising me to do this once as i will incur 2 costs, then again i made a large withdrawal again no agent or even the branch manager or the teller bothered advising me there would be a large cost to my withdrawal, when speaking to the very rude and unhelpful agent this morning he simply said well close your account if you need, as these funds cannot be reversed i feel that if someone had advised me or bothered to help my daily TRF amount could have been increased to do a EFT and i would have not sat with huge bank charges, i now need to fork out R3128.00 to finish work that my husband is now short of. This is my second bad experience with FNB and i will be closing my bank account i am a PVT banker and no benefits
