FNB are punishing their clients, for transferring money to other banks

Hi

I did a transfer of R10 400 to my absa account during August because my bond is with absa. Today I see my account and noticed that FNB is charging me fees for when I transfered money to absa. I will be moving banks if FNB is going to be charging me fees everytime I transfer money to other banks.This is unacceptable.
