How can we ignore you?

I have emailed FNB card three times now to find out what I need to do to close my credit card account. In a fashion that has become so typical of South African culture, they have simply ignored me. I therefore wish to state publicly that I will pay what I believe to be the balance owing on my card. Once this is done, I will notify FNB Card by email, advising them that final payment has been made and that as far as I am concerned, the account is closed. I will not entertain any further costs, real or imagined and no further correspondence will be entered into.
