FNB Accounts are useless and takes gives poor customer feedback and no response

I app**** for a FNB credit card at their N1 City branch, Cape Town on 30 October 2017. I went into the branch and filled in the papers required and the guy who helped me sent it to the application department. Up and till now I have not received any word from fnb in any form regarding my application. I have phoned in to the applications department on ********** 827 numerous times and each time it is a different excuse. I was told last week friday 10/11/2017 that I will have a response withing 48 hours meaning I will hear from fnb on tuesday 14/11/2017 to know what is happening and yet again I heard nothing from them. I had to phone in yesterday 15/11/2017 again to hear what is going on and I was told that my application is with collections regarding a previous card of mine which I paid up in full years ago. I was told that the collections department will contact me today 16/11/2017 at 16:15pm to discuss the matter and yet again no one called me today at all. I dont know if fnb doesn't appreciate their clients and the business they give them or not but it surely looks like fnb does not value their clients.
