Bad and ****** service from FNB!

Im so angry with FNB , i made an arrangement to pay R270 my account and they go and deduct R1618 om my account. when i query it they first **** i will get my refund and when i call to follow up that when they told me they can do whatever they want because us black people are not trustworthy and there is nothing i can do about that. i spoke to lloyd who was rude and referred me to her Manager Sulezi who was even more rude and ******. this is not the services i signed for when i join FNB. i want all my accounts to be cancelled with them as i wont allow to be racially abused like this because i have no power against them.
