Battling to open Business Account

Initially FNB was quick to respond to my request for a business account. I sent them all the required docs and then there was no reply ffrom their side for at least a week and I followed up. Then I started getting mails that docs were missing and I sent back the completed docs they reqquested. Still no reply from their side as to progress. Again I received mails re missing docs and they would actually attach blank docs where previously they had filled in the info. I responded (account.opening team) and asked them what docs they specifically still require and what I needed to provide still. No response to my mail. I called them again this morning and they promised to get back to me by 1 pm. They still haven't. So Im stuck as they are not telling me what docs they require and I need the account opened. I had to follow up continually with no solution from their side.
