bad attitude and service from staff

i went into this branch with a burnt R100 note hoping that they would exchange it for me as their client but was told that they can't help me. instead they referred me to other banks and the manager never even had the decency of talking to me and trying to come with a solution. instead he sent the guy at the door to deal with me. as their client i am very unhappy about this as i feel the situation could have handled better
