Fnb Bad For Business

On the 13th of May i realized that Fnb has closed my business account without notice, i have been doing work and expecting payment on the same account but they are sending me from pillar to post for the account to be reopened. I have been to the FNB Branch in Hartswater the Branch Manager told me that they cannot assist me, I send an email and also made calls to the business division. Fnb is awful and bad for SMME's
