Impossible for business to open a secondary savings account!

I have been a business account holder with FNB for 8 years, have 3 accounts, ct card, gold business account, money on call account, due to some grants I receive, I needed to create another call account, on the App I added a new call account to ring fence transactions - it is now been a week, five e-mails, 6 calls, and the acount is frown, I needed to fill in a Tax form, which I did, and still nothing, it is IMPOSSIBLE for an existing business with a good ct record and substantial funds in an account to open another savings account - it is beyond me!!!
