FNB Poor service

FNB credit card division is extremely useless , called them on the 24th May to settle and close my credit card , I was told by an employee the account is now settled and that she is requesting a closure , she advised it will take a few days to close, I call back after a few days another employee says balance is settled and it will take up to 14days to close , I call back yesterday and they advised its not closed and there's now a balance that obviously accumulated from the date it was suppose to have closed. he also now mentions I have to fill out a form which was not the case prior . its now past 14days and credit card is still not closed. I constantly have to call and speak to *********** staff who don't know what they doing and cant assist me. When I ask for a manager they say they cant transfer me .... such poor service
