BAD SERVICE

I app**** for a credit card application online, not sure what I did incorrectly I therefore could not continue with it. I believe FNB tried calling me a few times to continue with my application. A sms was sent to me on the 5th April, I called and was told that a specific consultant was dealing with my application. I was made to hold while I get transferred to her. Don't know how I was then transferred to the wrong person who asked me to wait and she will fetch the consultant dealing with my application to come take my call. She then told me she was on a call and will call me back at 10:00 till today NO CALL
