Credit phoned for

last week Nedbank called me to ask me if I need a credit card. I told them I am not interested but they can apply to see if it gets approved. they did the application and told me that its approved. after the phone was hung up they sent me an sms saying it was not successful. I am tired of Nedbank phoning me not taking no for an answer and then waste my time by doing the application when they know they will not approve it.
