FNB disappoints me again.

I had an account with Fnb and it apparently closed on the 11th of July, when i visit the branch to renew the account and use it i am told that because i will not be getting my salary paid with fnb they cannot assist me, i emailed an official complaint and two people got back to me regarding my complaint and the one reiterated that i cannot open this account again unless i want to have my salary go in it...I don’t undersTand how fnb operates as i am under the impression that no bank can force you to get paid into their bank account or just simply not have an account with them period...i told them I’m intending to use the account for a small side business of selling perfumes, stock and anything just to get me extra cash as I’m on maternity leave and i earn uif, they then suggested i open a business account which i assume has so many fees that I’ll end up not enjoying my little profit. If no one can assist with this it’s fine but i just want clarity on whether is this how fnb operates and if so are they allowed to impose hard selling on a client and literally force me to bank with them? On a side note i was a banking fnb client but then i moved to another bank because of this lack of service and no customer service whatsoever.
