Switching to FNB CREDIT CARD -NIGHTMARE/lies

As an existing Fnb customer I app**** for an FNB Platinum Credit card two weeks ago via the sales call center. I sent through the required documentation which had some access issues.I resent the documents to the email address provided twice with no respone. I called the call center yesterday they told me that no application exists now and I should create anew application by calling my premier banker or sales center as online application declines in basis that an application is in process .Talk about poor IT for a bank. The premier banker said they cant help i need to go to sales directly although its marketed that the premier banker can assist with all banking needs.Anyway I called the sales call center and im told my application is in progress now??? who do i believe??? If this is how you treat customers I think its best I move to a more straight forward bank
