Poor customer service

I am just disgusted by the level of service I received with the FNB credit card staff. I have been sent from pillar to post because I wanted to close my credit card. They don't actually know the procedure when closing an account. I have spoken to a lot of consultants, was told to hold the line and wait. but still I couldn't get assistance. when one wants to speak to management they hang up on me. I eventually spoke to Romancia who also couldn't assist and just tells me to go to a branch....so disappointed with FNB I am so glad I am moving banks.
