FNB won't help me

So I've been applying for a Zero business bank account and FNB NEVER got in touch with. I then went into the bank and the guy helped me open one. I asked him to help me open the other 2 that I needed, he told me he's not allowed and I must do it online. I told him that anything I do online doesn't work and he told me to go and try again. It's been 2 weeks still not being able to open another account. I then speak toTaryn in the FNB chat who tells me there's no limit to the amount of Zero business accounts one can have. I send her the screenshot showing her that it's telling me I can't open another one, and she disconnects from the chat. I then end up with another agent who tells me it's not his area of expertise. Like whyyyyy is he on the chat then? Nedbank directs you to the department you need t deal with while FNB literally doesn't help at all.
