FNB best with tech, worst with service

I tried closing my credit card a few weeks back. The consultant advised that it would take 5 to 21 working days to close the account. I expressed concerns, mentioning that the I don't want the card to run over into another billing cycle, because the admin and facility fees will be billed even though the card balance is zero. The consultant further advised that the card will be in process of being closed and no fees would be charged. THIS WAS NOT THE CASE. I asked her for the settlement amount which I transferred and put the account in credit. The card has still not been closed, admin and facility fees were levied even though I was told they won't be, and the consultants on the phone can't assist me with the matter. NO OTHER BANK takes 21 business days to close a credit card account; the action is immediate. Because of their poor administration, I am stuck with a card that I don't use, paying fees that I don't need to incur. Their banking methods that they offer are only a fraction better than other banks (if even) and is not worth the meagre service that you receive.
