FNB Refuses to Close my Account

I visited FNB branch with the intention to close my Debit and Credit card. The branch helped me with closing debit card and I was told to send an e-mail to ********** instructing them to close my credit card.

I sent an e-mail on the 1st of November 2018, until to days 12 days later I have only received what appeared to be an automated e-mail reply, which confirm having received my request.

The account is still not closed 12 days later, I sent request feedback on the 7th of November 5 days later no reply.

I am never doing business with FNB.
