Unhappy client

Had a terrible service when applying for re-advance on my existing standard bank home loan. They showed a high level of incompetence and a "don't care" attitude. I was asked to send the same form twice because someone who received it first decided not to do her work. Initially I was told that the payout process turnaround is 3 working days then later they said it actually takes 7 working days. I'm really dissapointed my this so called "Big bank"
