Why have a business banker when i cant call him

I have been trying to contact FNB / the branch for more than 6 weeks to organise a new credit card for my business. i have called the branch tried to talk to promise, the operational manager and the branch manager to try and get some resolution. but no one ever calls me back, or when i finally hear someone is in the branch the phone goes dead. <br> <br> due to my work hours i am unable to visit the branch, and in all honesty why have someone attend to your needs that does exactly the opposite. <br> <br> i am really unhappy with my current service.
