very unhelpful then they closed my application

Two weeks ago on a Thursday I went to FNB Greenstone to open a business account. The branch manager assisted but was very unwilling to help me. He then said I must not email my docs for the registration yet and that in 24 hours someone will call me. Nobody called So I contacted the call centre last Monday. The agent advised me to just give my I.D number , I kept being transferred with no assistance. I emailed my proof of residence and I.D to FNB as per the call centre. I was advised that this was all they needed. I then just got feedback a few days later \Application Declined"and the reason was that I didn't give all the documentation ???? This is extremely bad and I am being very inconvenienced due to FNB not bothering to assist as they promise to."""
