Very very bad service from FNB

I phoned FNB regarding a creditcard application and or overdraft. I have been told that i do not qualify and that i have bad record at transunion. I phoned trans union with concluded that i have no bad record at them and that the bank must give clear reasons why they do t want to approve. I phoned the bank again only to get the same answer and once i asked to speak to someone in charge i was put trough to transunion again by the bank. This is unexaptable. And im a premier client of FNB with all my products being with them and even paid 2 weeks in advance. Im going to the news papers with this and expose FNB cause this is no way to treat your loyal customers.
