FNB Business not jacked up to make your business banking easy

For many weeks, I have spoken on the phone, as well as use FNB chat, FNB contact email to fix my problem. I run a small business after hours. I work full time. I told them I never ever gave them my email address at the company I work at and they must remove and use the email i keep providing for all email communications related to my small business. In fact, my cell number (for SMS) and my banking App is where I want inContact messages. I am STILL receiving emails for transactions at my work. I dont mix the two, it is wrong for emails to come to my work! Besides this there are no bankers - so you speak to different people all the time. Sometimes they email that query is closed but it isnt resolved. If you have a personal bank account with that, they link your business account to your personal account because a business is not a person. So I cant see my card on my business profile. It is just messy and one should perhaps not have one bank for both your business account with your personal account
