Credit card application feedback

Unfortunately, I am writing a review once again as I've been unable to reach a credit card consultant at FNB for feedback and this is the only means in which I am able to receive assistance. This complaint relates to a previous complaint regarding my credit card application which was made 3 weeks ago. After struggling to obtain the status of my application, I eventually received a call from a consultant at the Credit Card Department (after my first Hellopeter complaint) last Wednesday with the status. She indicated that it was approved and would take 3 - 5 days for delivery of the Credit Card. Shortly after the call ended, I received an email to say there was an error processing my application and they would update me on the progress. Needless to say, I haven't heard back from them and it's been a week already. I also made 2 email inquiries to which I have received no response. I've tried calling, but keep getting transferred to consultant after consultant, and no-one seems to be able to assist me. My frustration level is very high as this is not the service I have generally received from FNB. Once again, the branch consultant has also been trying his best to assist, but without success from the credit card department.
