Shocking Business banking

I have been trying to contact my business banker for over two weeks. I keep on being referred to business banking call centre who has just told me the business banker I am dealing with is not even on the system. I was pre-approved for facilities that were,without warning, removed, my business banker via e-mail promised to get to the bottom of it. Yes the same e-mail address that is not on the FNB banking call centre's system. Now I am been moved from pillar to post via several call centres. If this is how FNB treats its business clients and private clients... I think it is time to move to another bank...absolutely shocking!!!!! Somebody needs to call me TODAY!
